If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
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.
The circumference of any circle is (pi) x (the circle's diameter).
10 x pi ie 3550/113 = 31.416"
diameter = circumference ÷ π = 10 ft ÷ π ≈ 3.18 ft
Circumference of circle: 10*pi = about 31.4 inches
The circumference of a 10-inch diameter circle is: 31.42 inches.
The circumference of a 10-inch diameter circle is: 31.4 inches.
If its diameter is 10 inches then its circumference is: diameter*pi If its radius is 10 inches then its circumference is: 2*pi*10
Circumference = pi * diameter c = 10*pi inches c ~= 31.4 inches
diameter = 10/pi inches
Circumference = diameter x pi = 31.416 inches (rounded)
31.42 inches.
The circumference of a 10 inch circle is: 31.416 inches(circumference = diameter x pi).
31.4 inches, ie 10 pi
About 30 inches
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
