Question

Find the area of the shaded region. Can I have the steps explained please?

Answer 1

76.3 cm²

Explanation:

step 1

• area of circle= πr²= 3.14*5²= 78.6 cm²

step 2

• area of 60° sector= 60/360*area of circle= 1/6*78.6= 13.1 cm²

step 3

• Area of equilateral triangle = √3/4a²= √3/4*5²= 10.83 cm²

step 4

• Area of circle - area of sector + area of triangle= 78.6 - 13.1 + 10.8= 76.3 cm²
