Question

Two circles have the same center C. (Circles that have the same center are called concentric.) The larger circle has a radius of 10 and the smaller circle has a radius of 6. Determine the area of the ring between these two circles.

Answer 1

A=64π

Explanation:

Area of a circle=πr²

π·10²-π·6²

=100π-36π

=64π

If you need to round it

64π≈201.062
