To find the area of half a circle, use the formula for a circle pi*r^2 divided by 2. pi = 3.14, r = radius (half the distance across the circle)

Let r be the radius of the circle. Then the perimeter of the half circle is pi*r + 2r. That is half of the circumference plus the diameter.

The perimeter of a circle is called the circumferenceTo find the circumference of a circle you do 2 times pi times radiusC = 2 * 3.14159 * 7 = 43.98inchesSince this is a half circle you have to take half of the circumference...you answer is 21.99inches

the radius is half of the diameter. and the middle of the circle is half way between this diameter.

Area of half a circle in square m = pi*radius2 divided by 2

The radius of a circle is half the diameter or half the circumference divided by pi (3.1416).

same as for a whole circle

you have find half

The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.

The radius of a circle is half its diameter (the measure of the circle from one side across to the other).
