Using 3.14 as Pi the area of circle is: 0
The formula for finding the area of a circle is pi times the radius squared. Let's find the radius of the circle. 100 pi/ pi= 100. Squarerooted, the radius is 10. The formula for finding the circumference of a circle is 2 times pi times the radius. So, plug in: 2 times pi times 10 equals 20 pi! Your final answer: 20 pi (or, if you use decimals, approximately 62.8)
100% or the Circumference
First find the radius and then the area will be pi*radius2 circumference = 2*pi*radius = 100 units radius = 100 divided by 2*pi = 15.91549431 units area = pi*15.915494312 = 795.7747155 square units So the area of the circle is 796 square units correct to three significant figures.
Divide the circumference of 62.8 by 2*pi to find the radius which is about 10 units Area of the circle: pi*10*10 = 100*pi square units
