Question

Find the area of the semicircle. Round your answer to the nearest hundredth.

Answer 1

Answer:

7.065

Step-by-step explanation:

The area for area is 3.14 x radius^2

so it would be 3.14 x 1.5^2

= 3.14 x 2.25

=7.065ft squared

and because this is not a full circle but a semi circle you would divide that answer by two so  7.065/2 =

3.5325ft squared

Hope this helped!! :)

Answer 2

Answer:

Step-by-step explanation:

d = 3 ft

r = 3/2 = 1.5 ft

$Area=\frac{1}{2}*\pi *r^{2}\\\\=\frac{1}{2}*3.14*1.5*1.5\\\\=\frac{7.065}{2}\\\\=3.5325$

= 3.53 ft²
