Question

What is the area of a circle with a circumference of 64π?

Answer 1

C = 2πr

64π = 2πr

32 = r

A = πr²

A = 32²π

Answer 2

Hi Jesset,

There's a formula for the circumference of a circle. You should look it up in your textbook (or other learning material). It's C = 2πr. Given the circumference, you can use this formula to determine the radius. Once you know the radius, there is another well known formula you can use to find the area.
