Question

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

Answer 1

7.065

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

Explanation:

d = 3 ft

r = 3/2 = 1.5 ft

`Area=(1)/(2)*\pi *r^(2)\\\\=(1)/(2)*3.14*1.5*1.5\\\\=(7.065)/(2)\\\\=3.5325`

= 3.53 ft²
