Question

in your computation, approximate its value as 3.14.
Find the area of the figure. If you need to use
Rectangle topped by a semicircle
15 in
12 in
406,08 sq. in.
b. 184.71 sq. in.
C. 293.04 sq. in
d. 236.52 sq. in

Answer 1

Answer: d

Step-by-step explanation:

Find the area of the rectangle.

$A=l*w\\A=(15in)(12in)\\A=180in^2$

Find the area of the base of the semicircle.

$A=\pi r^2$

12 in would be the diameter, divide by 2 to get the radius.

$\frac{12}{2}=6$

Plug this into the formula.

$A=(3.14)(6)^2\\A=113.04in^2$

Since we do not have a full circle but a semi one instead, we must divide our result by 2.

$\frac{113.04}{2}=56.52in^2$

Add both areas.

180+56.52=236.52$in^2$
