Question

Find the perimeter of this semi-circle with diameter,

d
= 32cm.
Give your answer as an expression in terms of
π

Answer 1

The perimeter of a semicircle with diameter d is given by the expression: (πd)/2 + d.

Substituting d = 32cm, we get:

(πd)/2 + d = (π*32)/2 + 32
= 16π + 32

Therefore, the perimeter of the semicircle is 16π + 32 cm
