Question

Find the area of the blue shaded region. Round your answer to the nearest hundredth

Answer 1

173.01

Explanation:

To area of a sector or portion of a circle is found using:

`A = (N)/(360) \pi r^2`

Substitute N = 50 and A = 27.93.

It becomes
`27.93 = (50)/(360) \pi r^2\\27.93 = 0.139 \pi r^2\\200.94 = \pi r^2`

The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.

200.94 - 27.93 = 173.01
