Question

Find the area of the circle. Round your answer to two decimal places, if necessary.

Answer 1

200.96 cm

Explanation:

Area of a circle:
`A=`
`\pi r^2`

Since we don't have the radius, we have to find it.

What you gave me is the diameter which is 16 (cm) I suppose.

Radius is half the diameter. Therefore we can divide the diameter by 2 to find the radius.

`16` ÷
`2=8`

This is our radius.

Plug this into the area formula.

`A=\pi r^2`

`A=(3.14)(8)^2`

`A=200.96cm`
