Question

Suppose the radius of a circle is 8. What is its area?

Answer 1

The Formula to find the Area of a circle using the radius is:

`A = \pi r^2`

r = 8
So:

`A = \pi r^2`

`A = \pi 8^2`

`A = \pi64`

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)
