Question

Two semicircles are attached to the sides of a rectangle as shown.

What is the area of this figure?

Use 3.14 for pi.

Answer 1

Answer:

Area = 194.24 square feet

Step-by-step explanation:

Area of the figure = 2 x Area of semi-circle + Area of rectangle

$r = \frac{diameter}{2} = \frac{8}{2} = 4ft\\\\Area \ of \ semi \ circle = \frac{1}{2} \pi r^2$

                               $= \frac{1}{2}\pi \times 16 = 8 \times 3.14 = 25.12ft^2$

 $Area \ of \ rectangle = length \times width = 18 \times 8 = 144ft^2$

Therefore , Area of the figure = 2 x 25.12 + 144 = 194.24 square feet                            

Answer 2

The answer is 169.12
Semi 1&2: 8*3.14=25.12
Rectangle: 18*8=144
144+25.12=169.12
I hope this helps!:)
