If by ' A 64 pi' you mean the Area. Then

A = 64pi

Since A = pi r^2 and 64 is 8^2

Then we can say r(radius)= 8

The circumference of a circle is

C = 2pir

Hence

C = 2 x 3.14 x 8

C = 16 x 3.14

C = 50.24 linear units.

The value for 'pi' at 3.14 is an approximation.

The circumference of any circle = diameter*pi or 2*pi*radius

I am not sure what you mean "A". In general, you can calculate the circumference of a circle:* By multiplying the diameter times pi, or

* By multiplying the radius times 2 times pi.
