The diameter of the semicircle will be twice the radius.
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.
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.
circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)
a sphere
The diameter of the semicircle will be twice the radius.
it is have 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.
It is its diameter plus half of its circumference
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
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.
It is half the circle's circumference plus its diameter.
circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)
it is the diameter

semicircle PQR of diameter 10 cm.semicircle PAB and BCR of diameter d1 and d2 respectively are inscribed in the semicircle PQR or such that the sum of d1 and d2 is equal to 10 cm. determine the relation between the lengths of arcs PQR,PAB, and BCR.
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.
