Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.

it is have the diameter
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
The answer will depend on what measure of the semicircle is 5 inches: its radius or 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.
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.

A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
The diameter of the semicircle will be twice the radius.
The diameter of the circle is 21.4 feet, approx.
Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).
it is the diameter
