Problem: Write an article based on this summary: Inflate a balloon with the gas you want to measure. Measure the balloon's circumference and radius. Use the volume of a sphere formula. Fill up another balloon with water to compare your results. Pour the water out and measure it.

Answer: If you're taking gas (like helium) from a tank, place the lip of the balloon tightly over the nozzle and fill it up. Or, if you want to measure air, just blow up the balloon using your mouth. Tie the end of the balloon in a tight knot when you're done. Wrap a cloth tape measure around the center of the balloon to check its circumference. To get the radius of your inflated balloon, place a ruler on each side of the center of the balloon, measure the distance between them, and divide it in half. For instance, you place your balloon between two rulers and find that the distance is 10 centimetres (3.9in). Divide this in half to get the radius, 5 centimetres (2.0in). Plug in your measurements into the basic formula for the volume (V) of a sphere, V = 43r3{\displaystyle {
rac {4}{3}}\pi r^{3}}. Plug the radius into the formula to get your sum. For instance,: V = 4353{\displaystyle {
rac {4}{3}}\pi 5^{3}}, or about 523.33 cm3{\displaystyle ^{3}} or 206.04 in3{\displaystyle ^{3}}. Place the lip of a balloon over a faucet and carefully run water into it. Stop when the balloon is the same size as the balloon filled with gas. If you accidentally put too much water in, carefully pour some out. It will be difficult to get the balloons to exactly the same size. To be more exact, wrap a cloth tape measure around the center of the water balloon to check its circumference. Adjust until it's the same as the gas-filled balloon's. Have someone help you measure the circumference of the water balloon while you hold it. Empty the balloon into a large measuring cup, beaker, or something else that can measure volume. Record the amount of water that was in the balloon. The volume of water will equal the volume of gas in the other balloon. If your water-filled balloon is the same size as the gas-filled balloon that you determined (via V = 43r3{\displaystyle {
rac {4}{3}}\pi r^{3}}) had a volume of 523.33 cm3{\displaystyle ^{3}}, then you should measure about 523 milliliters (18floz) of water poured out of it (1 ml = 1 cm3{\displaystyle ^{3}}).

Problem: Write an article based on this summary: Start working early. Go through the rules for the report. Decide what kind of a book you want.

Answer: Starting the night before the book report is due is way too late. Starting a few days before might also be too late unless you're an extremely fast reader. Give yourself time to read the book and understand it fully, then write your report. This might take a week or more to complete. This means you need to start looking for your book as soon as you can. Finding a book can take time, so don't rush it. You might find the perfect book, but it's checked out and has to be returned to the library. The amount of time you need for your book report will depend a lot on your personal pacing, the length of the book you choose, and your personal writing strategy. However, getting a head start never hurts. You need to follow any of the guidelines your teacher gave you for the report. Underline the parts that relate to choosing a book. What do you need to know? Some important information might be: Whether there is a minimum number of pages you need to read Whether the book should be fiction (made up) or non-fiction (true) Whether the book needs to be a specific genre, such as drama, science fiction, etc. Whether a graphic novel is an appropriate choice What kinds of information your teacher wants you to get out of the book There are millions of books out there, and between your school library and the public library, you have access to thousands. Within the parameters your teacher has set (number of pages, fiction or non-fiction), figure out what kind of book you would most like to read. It's important to choose something you want to read so that the assignment goes as smoothly as possible. Some possible questions you might ask yourself as you are choosing a book for a report are: Can you make the writing process easier by picking a book that ties into the work you're currently doing in class? Do you want something with a historical background, or something that takes place now? Is there a particular topic that interests you that might be a good choice animals, skateboarding, or music, for example? Do you like funny books or serious books? Do you like books about real people, or would you rather read fantasy or science fiction?

Problem: Write an article based on this summary: Build your outfit from your colored jeans. Add in a coordinating neutral top. Finish with a neutral-hued shoe.

Answer:
Neutral tops pair well with nearly all colored jeans, so you can choose any color pant to serve as the base of your look. For a more subtle option, try a dark or muted hue, such as a plummy purple, faded olive green, or mustard yellow. Neon colors and saturated primary hues, on the other hand, are a fun, easy way to create a bolder look. Try a cherry red, lime green, or bright turquoise jean to really stand out. The easiest way to start incorporating colored jeans into your wardrobe is to select a colored version of your everyday cut. Although skinny-leg colored jeans may be the most popular, you can find nearly any cut in a colored version. A crisp white button down or tee shirt make fool-proof partners for colored denim. Heather grey, cream, tan, and chambray are also good options. Consider the underlying color tone of your jeans when selecting the right neutral: blue-toned colors work well with cool-toned neutrals like black, gray, silver, and white, while red-toned colors are best with warm-toned neutrals like brown, gold, and cream. Although it's a neutral color, black can be more difficult to pair with colored jeans since it can appear too saturated, especially in contrast to light pastel hues. If the black isn't working for you, try a dark grey or navy instead. Pastel jeans and deep tones work best with conservative blouses or a button-down shirt. A light mint green jean will pair well with a traditional denim button-down shirt, or a deep olive green might look nice with lacy off-white blouse. A bright jean color matches well with bolder style shirts. Funky necklines, peplum tops, and embellishments such as ruffles or sequins can hold their own against bright jeans. To keep your look easy and understated, opt for flats, sandals, or loafers in a neutral color such as brown, tan, or nude. For a slightly more unexpected look, consider a pair of metallic flats or pumps. Rose gold, silver, and bronze are still neutral colors so will pair well with most colored jeans.
