Question

Find the area of the figure. Use 3.14 for x, and round your answer to the nearest tenth.

Rectangle with a semicircle cut out of one end

4.0 height
8.0 length

A.28.3
B.13.8
C.27.6
D.25.7

Answer 1

D. 25.7 sq.ft

Explanation:

Area of the Figure = Area of Rectangle - Area of Semi Circle

Area of Rectangle = LW = 8*4 = 32 sq.ft

Area of Semicircle = 0.5*π*r² = 0.5*3.14*2² = 6.28 sq.ft

Area of the Figure = 32-6.28 = 25.72 ≈25.7
