Ques: Passage: World population has experienced continuous growth since the end of the Great Famine of 1315 -- 17 and the Black Death in 1350, when it was near 370 million.

The growth rate has declined to 1.18 % between 2010-2015 and is projected to decline to 0.13 % by the year 2100. Total annual births were highest in the late 1980s at about 139 million, and are now expected to remain essentially constant at their 2011 level of 135 million, while deaths number 56 million per year and are expected to increase to 80 million per year by 2040. World population reached 7 billion on October 31, 2011 according to the United Nations Population Fund, and on March 12, 2012 according to the United States Census Bureau.

The author used a variety of pre-existing sources, such as conflict stories (Mark 2: 1 -- 3: 6), apocalyptic discourse (4: 1 -- 35), and collections of sayings (although not the Gospel of Thomas and probably not the Q source).

Ans: approximately 695,700 kilometres ( 432,300 miles )
Ques: The solar radius is approximately 695,700 kilometres (432,300 miles), which is about 10 times the average radius of Jupiter, 110 times the radius of the Earth, and 1 / 215th of an astronomical unit, the distance of the Earth from the Sun. It varies slightly from pole to equator due to its rotation, which induces an oblateness in the order of 10 parts per million. (See 1 gigametre for similar distances.)

What is the solar radius of the sun?
CoT: To answer this question, we should know that: The solar radius is approximately 695,700 kilometres (432,300 miles), which is about 10 times the average radius of Jupiter, 110 times the radius of the Earth, and 1 / 215th of an astronomical unit, the distance of the Earth from the Sun.
