Question

A circular plate has a radius of 13 centimeters.

What is the area of the plate?

Use 3.14 for π .


______ cm²

Answer 1

The formula for the area of a circle is:

`\pi {r}^(2)`
If you plug in 13 for the radius and 3.14 for pi, you get:

`3.14 * {13}^(2) \\ 3.14 * 169 \\ 530.66`

Answer 2

i think its 530.929cm.
The formula is (pie) (radius to the second power)
if you need the steps just tell me i will gladly do it for you so you will understand next time.
