Question

What is the area of the shaded portion of the circle?

Answer 1

Answer: 18.27

Explanation:

Area of Shaded = Area of pie - Area of triangle

Area of pie = (angle)/360 *
`\pi \\` r²

Area of pie = 90/360 *
`\pi` * 8²

Area of pie = 50.27

Area of triangle = 1/2 bh

Area of triangle = 1/2 8(8)

Area of triangle = 32

Area of shaded = 50.27 - 32

Area of shaded = 18.27
