Question: is circumference area of a circle?
Answer: The area of a circle is given by the formula A = π r2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r. ... Now we use this to replace r in the first equation: A = π [ C / (2 π ) ]2. When we simplify this, we get A = C2 / (4 π).
