Question

A circle has a radius of 9 ft.

What is the approximate area of the circle? Use 3.14 to approximate pi. Write the answer to the nearest hundredth.


I am thinking the answer is 254ft squared

Answer 1

It is 254.47

Answer 2

if we round to the nearest hundredth would that be 254?

Answer 3

Formula:

\(A = \pi r^2\)

Plug in what we know:

\(A = (3.14)(9^2)\)

Multiply 3.14 * 9 * 9
