Question

Find the shaded area. Round your answer to the nearest tenth, if necessary.

Use 3.14 for pi.
Area of the Rectangle =


Area of the Circle =


Total Shaded Area =

Answer 1

Area of the rectangle - 144 in^2

Area of the circle - 28,26 in^2

Total shaded area - 115,74 in^2

Explanation:

`a(rectangle) = 18 * 8 = 144 \: {in}^(2)`

`a(circle) = \pi * {r}^(2) = {3}^(2) * \pi = 9\pi = 9 * 3.14 = 28.26 \: {in}^(2)`

`a(shaded) = a(rectangle) - a(circle)`

`a(shaded) = 144 -28.26 = 115.74 \: {in}^(2)`
