By definition, the perimeter of a semicircle is given by:
\(P = ( \pi ) * (r) + d\)
Where,
d: diameter of the semicircle
r: radius of the semicircle.
The radius of the semicircle is given by:
\(r = d / 2\)
Where,
d: diameter of the semicircle
Substituting values:
\(r = 64/2
r = 32 m\)
Then, the perimeter is:
\(P = (3.14) * (32) + 64
P =
164.48 m\)
Answer:
The perimeter of the semicurcle is given by:
P =
164.48 m
