Perimeter of a semicircle is the length of the half-circle plus the diameter.

The whole circle would have a length of diameter times pi, but since it's only half...

Perimeter of semicircle = (1/2*pi*D) + D

8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.


What is the perimeter of a semicircle if the diameter is 8cm?

Ah, what a lovely question! To find the perimeter of a semicircle, you'll need to add the curved part (half the circumference of a full circle) to the diameter of the semicircle. Since the diameter is 8cm, the radius is half of that, which is 4cm. The perimeter would then be half the circumference of a full circle (pi times the diameter) plus the diameter, giving you a total of 4π + 8 cm.


If the base of a semicircle is a feet What is its perimeter?

The circumference of a circle = 2π r = π a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the perimeter of the circle + the base length The perimeter of the semicircle = πa/2 + a = a(1 + π /2) feet

What is the perimeter of a semicircle with radius 8cm?

A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm
