8*pi + 16 = 41.13 cm (approx)
It depends on whether 8 cm is the radius or diameter of the semicircle.
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
dot know ..... just tell me the answer stupid computer
That depends on what you mean by a "20 ft semicircle".A semi-circle is a half circle.A 20 ft circle could be:A circle of diameter 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2π 20 ft + 20 ft= 10π + 20 ft≈ 51.42 ftA circle of radius 20 ftThe perimeter of the semicircle is half the circumference plus double the radius → perimeter = 1/2 2π 20 ft + 2 x 20 ft= 20π + 40 ft≈ 102.08 ftA circle of circumference 20 ftThe perimeter of the semicircle is half the circumference plus the diameter → perimeter = 1/2 20 ft + 20 ft ÷ π= 10 ft + 20/π ft≈ 16.37 ftHowever, if a 20 ft circle is a circle with a circumference (= perimeter) of 20 ft then a 20 ft semi-circle could be a semicircle with a perimeter of 20 ft→ perimeter = 20 ft
12+12=24 8+8= +16 The perimeter =40cm2
6 sides, times 8cm per side= 48cm
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
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.
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

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.
The perimeter of a semicircle with radius R is pi*R + 2*R = R*(pi + 2)
Divide the perimeter length by 4 ie 8cm and square the result ie 8cm x 8cm = 64sq cm
42cm
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
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.
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
