Question

The radius of a circle is 8 centimeters. What is the circle's area?

Answer 1

So the area of a circle can be found with the equation A=πr2

If the radius is 8 we plug 8 into the equation

A=π8^2

We then square 8 which is 64

We now have
A= π64

We multiply 64 and pie so

A=201.06

Answer 2

Area of circle= pi x radius squared

R=8

8 x 8= 64

64 x pi= 201.06 squared cm
