Question

His composite shape is a rectangle with a semicircle attached on one end. The diameter of the semicircle is 6 feet.

What is the approximate area of this composite figure? Use 3.14 for
`\pi` and round to the nearest whole number.

Answer 1

We can solve by figuring the area of the rectangle then add it to the area of the semicircle.

Area of the rectangle: length · width = 6 · 10 = 60 ft²

Area of the semicircle: (πd²)/8 = (3.14 · 6²)/8 = (3.14 · 36)/8 = 14.13 ft²

Total area of the figure: 60 + 14.13 = 74.13 ft² ≈ 74 ft²

Answer 2

The total area, rounded, would be 74 i believe
