The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².
The area of the sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches is: 25 square inches.
A 10-inch circle has an area of 78.54 inches2
The area is 78.5 square inches.
100pi, or approximately 314.
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
Area of a circle = pi * r^2 So - for yours: Area = 3.14 * 25 =78.5 square inches
Area of circle: pi*10^2 = 100*pi square inches
Area = Pi multiplied by the radius squared Circumference = Pi multiplied by the diameter r = 10 in./2 = 5 in. A = (3.1415)(5 in.)(5 in.) = 78.54 in.2 C = (3.1415)(10 in.) = 31.42 in. Therefore, a small circle with a diameter of 10 inches has an area of about 78.54 inches squared and a circumference of about 31.42 inches.
Diameter is 10 inches.
The area of a circle with a diameter of 10 centimeters is: 78.54 cm2
radius = square root of (78.5/pi) = 4.998732446 diameter = 2*4.998732446 = 9.997464892 or about 10 inches
