What is the perimeter of a semicircle that is 5 inches?
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
What is the perimeter of a semicircle?
dot know ..... just tell me the answer stupid computer
What would the perimeter of a 20ft semicircle be?
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
Perimeter of a rectangle 12cm x 8cm?
12+12=24 8+8= +16 The perimeter =40cm2
What is the perimeter of a regular hexagon with side length 8 cm?
6 sides, times 8cm per side= 48cm
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?
What is the perimeter of a three Quarter with 3m radius
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 perimeter of 8Cm?
6
What is the perimeter 7cm 8cm 12cm?
It is: 7+8+12 = 27 cm
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)
What is the area of a square whose perimeter is 32cm?
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
Fing the area of a square if the perimeter of that sqauare is 32 cm?
Divide the perimeter length by 4 ie 8cm and square the result ie 8cm x 8cm = 64sq cm
What is the perimeter of a rectangle 13Cm by 8Cm?
42cm
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 of a semicircle that is 5 inches?
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
