Question

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.
Area of semicircle =


Area of rectangle =


TOTAL area of composite figue =

Answer 1

The answer to your problem is, Area = 104.1 square feet.

Explanation:

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

`A_(sc) = (1)/(2) tt r^(2)`

Radius is half the diameter of 6ft.

`A_(sc) = (1)/(2) tt ( 3^(2) ) = 14.13ft^(2)`

Area of the rectangle:

`A_(r) = lw = 15 * 6 = 90ft^(2)`

Add them:

`90 + 14.13 = 104.13`

Round to the nearest tenth (one decimal place)

Which is 104.1

Thus the answer to your problem is 104.1 of 104.13
