Answer:

113.4325 m^2

Step-by-step explanation:

The diameter is 17m

d =2r

17 = 2r

Divide by 2

17/2 = 2r/2

8.5 =r

A semicircle is 1/2 of a circle, so 1/2 of the area of a circle is the area of a semicircle

A circle = pi r^2

1/2 A circle = 1/2 pi r^2

                   = 1/2 (3.14) (8.5)^2

                  = .5 * 3.14 * 72.25

                  =113.4325 m^2
