How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
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 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.
What is a semicircle?
a semicircle is half of a circle... so like a circle cut in half, in a straight line. just for some information you may also need in the future: area of a semicircle: multiply the radius by itself and then multiply that by pi (approx. 3.14). divide that by 2. perimeter (circumference) of a semicircle: pi times radius. hope that helps.
What is the formula for finding the distance around A semicircle?
It is: (pi*radius)+(diameter)
