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 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


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

To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 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

How do you find the perimeter of a shape that has a semicircle?

To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.


What is the formula of a semicircle in perimeter?

The perimeter of a semicircle with radius R is pi*R + 2*R = R*(pi + 2)

Perimeter of a semicircle when the Diameter is 8?

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


What is the perimeter for 8cm 6cm 2cm 5cm 3cm 8cm?

To find the perimeter of a shape, you simply add up the lengths of all its sides. In this case, the perimeter would be 8cm + 6cm + 2cm + 5cm + 3cm + 8cm, which equals 32cm. So, the perimeter of the shape with sides measuring 8cm, 6cm, 2cm, 5cm, 3cm, and 8cm is 32cm.
