What does the radius of a circle measure?
Half the diameter of a circle called the semicircle
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
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.
What is the approximate area of a semicircle with a diameter of 22 inches?
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
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its radius
What does the radius of a circle measure?

How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
What is the diameter of a semicircle with a radius of 5 ft?
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
What is the perimeter of a semicircle with radius 8cm?
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

How do you find the radius of a semicircle?
it is have the diameter

What is the semi circle radius 10cm?
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
How do the the radius and diameter of a circle compare?
The diameter of a circle is twice its radius
If the radius of a circle is r what is the diameter of the circle?
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
What is the perimeter of a semicircle that is 5 inches?
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
