Question

Find the approximate area of the shaded region below, consisting of a right triangle with a circle cut out of it. Use 3.14 as an approximation for pi.

A.544 square meters

B.1,486 square meters

C.3,286 square meters

D.314 square meters

Answer 1

Answer: 1486m²

Explanation:

area of a circle = π(D)²/4 = 3.14 * 400/4 = 314m²

Area of the triangle = 1/2(base * height)

Area of the triangle = 1/2(60 * 60)= 1800m²

Area of the shaded region = 1800 - 314 = 1486m²
