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 find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find the radius if given the diameter?
Divide the diameter by 2.
When given the radius of a circle how do you find the diameter?
You times the radius by 2.
How do you find the radius of a circle when the diameter is given?
Divide the diameter by 2.

How do you find the radius if you are given the radius?
I guess you mean:"How do you find the radius if you are given the diameter?"You take the diameter and divide it by 2.
How do you find the radius if the diameter is given?
the radius is half the diameter
How do you find radius when given a diameter?
The radius is half the diameter.
How do you find a radius if the diameter is given?
divide diameter by 2 = radius
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
How do you find a radius given the diameter?
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
How do you find the radius with the given diameter?
radius is half diameter...so divide diameter by 2!!!
How do you find diameter when given radius?
you have multiplythe radius by 2 to get the diameter
How do you find the diameter of a circle given the radius?
Double the radius
How do you find the radius if given the diameter?
Divide the diameter by 2.
