What is the equation to solve the area of a semicircle?

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

How do you find the area of circle when its half of the circle?

What is the perimeter and area of a semi circle that has a radius of 4 inches?

The circumference of a circle is 2{pi}r. So, for a semicircle it is half this, that is {pi}r. The perimeter of the semicircle is the round bit ({pi}r) plus a diameter of the circle (2r) perimeter = {pi}4 + 2 x 4 ~= 20.6 in Area of a circle is {pi}r2, so for a semicircle it is half this. area ={pi}42 / 2 ~= 25.1 in2.

What is the area of a 12 inch semicircle?

Area in square inches = (pi*radius^2)/2

How do you find the circumference of a semicicle?

circumference of a semicircle = pi * diameter / 2 (pi multiplied by the diameter and divided by 2)

That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/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.
