Question

Perimeter and area

What is the area of the square, circle, and shaded region?
A)
B)
C)

Answer 1

(a) The side length of the square is 8 m, so its area is 64 square m.

(b) The radius of the circle is 4 m, so its area is
`(\pi)(4^(2))=16\pi` square m.

(c) Subtracting areas, we get the area of the shaded region is
`64-16\pi` square m.
