It's half of the area of the whole circle...

Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2

Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.

Using 3.14 as Pi the area of circle is: 530.66

The radius squared. The radius is half of the diameter

The formula for the area of a circle is A = pi x r2 where r is the radius. If the diameter of the circle is 10 meters, then the radius is half that amount or 5 meters. Plug that value into the formula for r, using 3.14 as an approximation for pi. The area is 3.14 x 52 or about 78.5.

Half of that.

If a circle has a diameter of 67.5 m, then the radius is half of that. Half of 57.5 is 28.75

No. The area of a circle is 3.142 x radius x radius (radius is half the diameter).

The radius of the circle is half of the diameter, so it is 4 meters. To find the area of the circle, we can use the formula A = πr^2. Substituting the value of the radius, the area of the circle is therefore A = 3.14 * (4)^2 = 3.14 * 16 = 50.24 square meters.

16 square meters, to 2 significant digits. The area of a circle is calculated as the value pi (3.1416...) times the square of the radius of that circle. In this case, where a circle has a diameter of 4.2 meters, the radius, which is half the diameter, will be 2.1 meters. So to solve for the area (A) of this circle: A = pi x r2 = 3.1416 x 2.1m x 2.1m = 15.954456m2 = 16 square meters.

area of a circle is pi times radius squared. the radius is 11 feet. the area ofthe circle would be 380ft2 since it is a half circle you take half of 380... your answer is 190ft2

The area of a circle is calculated as the value pi(3.1416...) times the square of the radius of that circle.In this case, where a circle has a diameter of 55 meters, the radius, which is half the diameter, will be 25 meters.So to solve for the area (A) of this circle:A = pi x r2 = 3.1416 x 25m x 25m = 1963.5m2 = 1963.5 square meters.

area of a circle = pi*r^2 with pi being 3.1415926535..... that is the ratio between the diameter of the circle and it's circumference. r stands for radius (half the diameter if you didn't know) so for this circle to find the area all you have to do is 12 (half of 24 the diameter to find the radius) , then square it (144) then times it by pi which equals approximately 452.39 meters^2

It's half of the area of the whole circle...

Area of a circle is pi*radius^2. So if the radius is measured in feet, the area (or the square footage) of a half circle is: (pi*r^2)/2

The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
