Twice as big.
The diameter of the semicircle will be twice the radius.
Half the diameter of a circle called the 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.
You can multiply the radius by pi to get the length of the semicircle.
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.
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
it is have the diameter
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
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: (pi*radius)+(diameter)
Half the diameter of a circle called the semicircle
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
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.
8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.
Calculating the radius of a semicircle depends on what information about the semicircle is given.
No, only if the diameter is bigger than the radius is the radius smaller than the diameter.
