multiple the diameter by 2 to get the radius, then use your equation and go from there
The diameter of the semicircle will be twice the radius.
Easy, you find the area of the circle (Pi X Radius squared) and then multiply it by the height. Your question asks about using the diameter...the radius is half of the diameter.
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
Divide the diameter by 2.
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.
the radius is half the diameter
The radius is half the diameter.
half the diameter and then get the radius times pi and square it
multiple the diameter by 2 to get the radius, then use your equation and go from there
divide diameter by 2 = radius
Given the radius, r, the area is pi*r^2.If given the diameter d, the radius is d/r so the area is 0.25*pi*d^2If given the circumference, c, the radius is c/(2*pi), so area = 0.25*(c^2)/pi
The diameter of the semicircle will be twice the radius.
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
radius is half diameter...so divide diameter by 2!!!
