Question

THE RIGHT ANSWERRRRRR

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

Example: 103.45 rounded to tenths place is 103.5

Use 3.14 for pi in finding the area of the semicircle.

Answer 1

Area of semicircle = 1/2 the area of a circle:

`A_(sc)=(1)/(2) \pi r^(2)`
radius is half the diameter of 6ft.

`A_(sc) = (1)/(2) \pi (3^(2) )=14.13 ft^(2) .`
Area of the rectangle:

`A_(r) =lw=15*6=90 ft^(2) .`
Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.
