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 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.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
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 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.
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
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.
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 the approximate circumference of a semicircle with a radius of 30 centimeters?
You can multiply the radius by pi to get the length of the semicircle.
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.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/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.
How do you find the perimeter of a semicircle?
The circumference of a semicircle is pi times the radius plus the diameter.
What is the semi circle radius 10cm?
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
What is the area of a semicircle whose radius is 5 cm?
50.25cm
