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
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
What is a semicircle?
a semicircle is half of a circle... so like a circle cut in half, in a straight line. just for some information you may also need in the future: area of a semicircle: multiply the radius by itself and then multiply that by pi (approx. 3.14). divide that by 2. perimeter (circumference) of a semicircle: pi times radius. hope that helps.
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 diameter of a semicircle with a radius of 5 ft?
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
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 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 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 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 if it's radius is 280 cm?
Perimeter = (pi*280)+560 = 1439.645943 cm
What is the perimeter of a 8cm semicircle?
8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.
How do you find the perimeter of a semicircle?
The circumference of a semicircle is pi times the radius plus the diameter.
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
The radius of the semicircle is 5 feet and the dimensions of the rectangle are 10 ft by 16 ft The semicircle is attached to the width of it What is the perimeter?
Perimeter = (2*pi*5*1/2)+10+16+16 = 57.70796327 or 58 feet

How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the 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
