Question

If the perimeter of the semi circular park is 72 m find area and radius

Answer 1

p. of semi circle = πr
72m=3.14r
r = 72/3.14
r=22.92m
area=πr2/2
3.14*22.92*22.92/2
area=824.76m2

Answer 2

perimeter of semicircular park =72
I.e..., Pi * r =72
r=72/3.14
radius→▶ r=23
area of semicircular park =(Pi * r^2)/2
=(3.14 * 23^2)/2
=(3.14 * 529)/2
area→▶ =830.5

hope it will help u : )
