Area = pi*3/82 = 0.4417864669 or 0.442 correct to three decimal places
9pi (about 28 and one quarter) square feet.
If its diameter is 14 then its area is: pi*72 = 153.938 square inches to three decimal places
The area of a circle with a diameter of 9.4 m is: 69.4 m2
The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.
If the area of a circle is 8pi, its diameter is: 5.657 units.
The area of a circle with a diameter of 4.75 is: 17.72 square units.
What a strange question. A circle does not have a length or a width. It has a diameter and that all.
9pi (about 28 and one quarter) square feet.
The diameter of a circle with an area of 37.68 is 6.92
If its diameter is 14 then its area is: pi*72 = 153.938 square inches to three decimal places
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.
If the area of a circle is 8pi, its diameter is: 5.657 units.
The diameter of a circle whose area is 200.96 is: 16
