What is area of semicircle?

Anonymous

∙ 13y ago

Updated: 4/28/2022

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 the area of a semicircle when the radius is 21?

The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.

What is the diameter of a 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.

What is the area of each semicircle to the nearest square meter?

Needs more information!

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.
