Question

The circumference of a circle is 16 π inches. Show how you can use this information to calculate the same circles area.

Answer 1

`64\pi` in²

Explanation:

The circumference of a circle is
`2\pi r`, which means that in this case, r = 8 (since 2r = 16). The equation for the area of a circle is
`\pi r^(2)`, so therefore the area of this circle is
`8^(2) \pi = 64\pi`
