Area bounded by the concentric circles is 200.96 inches

Step-by-step explanation:

Step 1 :

Given

radius of the outer circle = 10 inches

So the area of this circle  = × r² =  = × 10² = 100  

radius of the inner circle  = 6 inches

So the area of this circle  = × r² =  = × 6² = 36  

Step 2 :

The area bounded by concentric circles can be found by subtracting the inner circle's area from the outer circle's area.

Hence area bounded by the concentric circles = 100   - 36   = 64   = 64 * 3.14 = 200.96 inches

Step 3 :
