The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a 9-inch diameter circle would be 4.5 inches. Plugging this into the formula, the area of the circle would be A = π(4.5)^2 = 63.585 square inches.
Area = pi*9*9 square inches
The circumference of 9 inch diameter circle is about 28.27 inches.
The area of a circle with a diameter of 9 inches is: 63.62 square inches.
The area of a 9-meter diameter circle is 63.617 square meters.
The formula for the area of a circle is A = PI R squared.Pi is about 3.1416R is the radius, half the diameter or 18/2 = 9A= 3.1416 * 9 * 9 = 254.4696 Using more digits in PI will give slightly different answers such as3.14159265359 * 9 * 9 = 254.469004941 which still is about the same value.So the area of an an 8 inch diameter circle (rounded) is about 254.5 square inches
If you mean a circle area than A = 63.61725 inch². Area A = pi times diameter² / 4.
Area = pi*9*9 square inches
The circumference of 9 inch diameter circle is about 28.27 inches.
The area of a circle with a diameter of 9 inches is: 63.62 square inches.
A circle with a diameter of 9 yards has an area of 63.62 square yards.
A circle with a diameter of 14 feet 9 inches has an area of: 170.87 square feet.
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
(9 pi) inches is.
The formula for finding the area of a circle is pi * r², where pi = 3.14; * = multiply; r = 1/2 of the diameter; and ² = squared (multiplied by itself). An example of how to calculate the area of a circle with a 6 inch diameter (3 inch radius): a = Pi * r² a = 3.14 * 3² a = 3.14 * 9 a = 28.26
3.14
The area of a 9-meter diameter circle is 63.617 square meters.
A=pi X radius squared 3.14 X 9=28.26 sq. inches
