A circle with a diameter of 11 inches has an area of 95.03 square inches.
The circumference and area of a circle with diameter of 12 inches are:C = 37.7 inchesA = 113.1 square inches
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
Well, darling, to find the area of a circle, you use the formula A = πr^2. Since the diameter is 8 inches, the radius would be half of that, which is 4 inches. Plug that into the formula, and you get an area of 16π square inches. Voila!
About 153.86 square in. To find out the area of a circle do: r^2*pi.
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle. Since the diameter is 60 inches, the radius is half of that, which is 30 inches. Plugging this into the formula, A = π(30)^2 = 900π square inches. Therefore, the area of the circle is 900π square inches.
im assuming your circle has a diameter of 1/4 inches to find sq in just find the area since the area is the definition of square inches. area = (3.14159) * (.252) = 0.196349375sq in
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
a circle with circumference of 25.56 inches.
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
