Circumference is simply pi times the diameter. The approximate value of pi is 3.14, so for a circle 4 feet in diameter, the circumference is 4 x 3.14 = 12.56 feet, approximately.
r = 34.83 ft C = 218.9 ft
The diameter of a circle with a 48 feet circumference is: 15.28 feet (circumference divided by Pi = diameter).
The circumference of a circle with a diameter of nine feet is: 28.27 feet (diameter x Pi = circumference).
Circumference = 2*38*pi feet

35 feet.
The volume of a cylinder when the inside circumference is 12 feet and height is 8 feet is: 91.7 cubic feet.
The sphere's approximate volume is 523.6 cubic feet.
If its the diameter you have, then take pi as 3, multiply by the diameter, in this case 3 * 9 = 27 feet circumference approx.
It is 10.5 feet.
Assuming 30 feet is the diameter, its 94.2ft
Circumference (perimeter) = pi * diameter = 3.141592654 * 21 = 65.973 feet Surface area = pi * radius 2 = 3.141592654 * 10.5 * 10.5 = 346.36 sq. feet Volume (cu feet) = 346.36 * depth in feet . Volume * 7.4805 = US gallons Volume * 6.2288 = imp gallons (results approximate)
First we have to find the radius by dividing the circumference by 2*pi which works out as 1.909859317 feet Volume of a sphere = 4/3*pi*radius3 Volume = 29.18050088 or 29.2 cubic feet to the nearest tenth
