What is the diameter of a circle with a radius of 21 ft?
If radius=21 ft, then diameter = 2*radius = 42 ft
Find the volume of a square pyramid with base edges of 21 feet and a height of 18 feet?
Volume of this pyramid is (area of base) x (height) / 3. The area of the base (square) is (edge)2 So (21 ft)2 * (18 ft)/3 = 26586 cubic feet
How many square feet in a 21' foot diameter circle?

Diameter of 66 inch circumference?
To find the diameter of a circle with a circumference of 66 inches, you can use the formula C = πd, where C is the circumference and d is the diameter. Rearranging the formula to solve for d, you get d = C / π. Plugging in the circumference of 66 inches, the diameter would be 66 / π ≈ 21 inches.
How many gallons of water are in an area with a 42 inch diameter circle that is 96 inches tall?
The volume of a cylinder is (pi) x (radius of the base)2 x (height)Radius = 1/2 diameterVolume of the tall tin-can you've described is (pi) x (21)2 x (96) = 133,002.5 cubic inches = 575.77 gallons. (rounded)That's the volume of the shape you described. We have no way of knowinghow much water may be in it at any given time. For all we know, it may beempty, or full of chicken feathers etc.
