Question

Find the area of the shaded figure in the diagram below. Use 3.14 for π and round your answer to the nearest hundredth.

A. 39.57in^2
B. 66.89 in^2
C. 200.67 in^2
D. 118.72 in^2

Answer 1

D

Explanation:

diameter of 1 circle = 21.3/3= 7.1

radius of 1 circle= 7.1/3=3.55

area of 1 circle =πr^2=3.14× (3.55)^2=39.57

area of 3 circle= 39.57×3=118.72

therefore,area of shaded portion= area of 3 circle =118.72
