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 the equation to solve the area of a semicircle?

Area of a semicircle = (pi*radius^2)/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.


How do you calculate the area of a semicicrcle?

If the radius of the circle is r, then the area of the WHOLE circle is pi*r2 so the area of the semicircle is half that, ie 0.5*pi*r2


What is the area of a semicircle whose radius is 5 cm?

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.
