The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part. Give your answer as a completely
simplified exact value in terms of pie (no approximations).

32pi - 64

Step-by-step explanation:

The two UNshaded areas are equal to each other. Each one is the

Area (square) - 1/4 Area(circle)

64 - 1/4 (64pi)

64 - 16pi

There are 2 of these unshaded pieces in this question.

Area (square) - 2 (64 - 16pi)

64 - 128 + 32pi

= -64 + 32pi

Area = 32pi - 64

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
