Sagot :

Answer: the fencing need to be 125 feet
Solution:
Radius(r)=25 ft
Perimeter(P)=?

We have,
Perimeter of a semi-circle(P)= πr+2r
=(22/7)*25+2*25[Since, π is approxiamately equals to 22/7]
=22*25/7 +50
=600/7
=85.714 ft

Since the fencing is done around the semi-circular garden, the length of fencing=perimeter of the garden.

Therefore, 85.714 ft of fencing is required to go around the garden.
