Answer:

A) 226.98 in^2

B) 120 in^2

C) 106.98 in^2

Explanation:

A) The diagonal of the rectangle is the diameter of the circle. The area can be found using the formula ...

A = (π/4)d^2

A = (π/4)(17 in)^2 = 72.25π in^2 ≈ 226.98 in^2

__

B) The area of the rectangle is the product of its length and width:

A = LW

A = (15 in)(8 in) = 120 in^2

__

C) The shaded area is the difference between the circle area and the rectangle area:

shaded area = (226.98 in^2) -(120 in^2) = 106.98 in^2
