Find the exact area of the region bounded by two concentric circles with radii 10inches and 6inches

The exact area of the region bounded by two concentric circles is

Step-by-step explanation:

we know that

To find the area of the region bounded by two concentric circles, subtract the area of the less circle from the area of the greater circle

Remember that the area of a circle is equal to

so

12.4, 12.387, 12.26, 12.252, 6.241, 6.2, 6.015, 6.009, 1.411, 1.2, 1.056, 1.007, 0.31,   0.13, 0.5, 0.04
