you need to use the formula for volume which is V = πr2h, where r is the radius of the tank and h is the height.

the question: a cylindrical tank has a circumference of 13.2, determine the diameter and the cross-sectional area of the tank?
Only circles (or spheres) have a diameter
Wrap a string around the tree and measure the length. Divide the length by pi (~3.14159); that is an approximation of the diameter (if the tree really was cylindrical. Cut the tree down measure the stump.

The formula to find the volume of a right cylinder is height times area of the circular base. This volume in cubic feet is then multiplied by 7.48 to find the number of gallons.
231 cubic inches = 1 gallon. To find out how many gallons will fill the tank, you must multiply the area of the tank by the depth to find the volume and then divide by 231 to figure how many gallons will fill it: volume of 41 inch dia by 93 inch depth = 122,783.93 cubic inches divided by 231 = 531.532 gallons. PS: I assumed the 41 inches diameter is the inside diameter. If it is the outside diameter, the thickeness of the walls need to be subtracted in order to find the inside diameter for a better calculation. The formula for Area is R (radius = half of diameter) squared X Pi (3.1416).

You need three dimensions to calculate the volume: Width, Length, and Height. Multiple the three dimensions together to find the volume then multiply by 7.481 (gallons of water per cubic foot). HINT: Be sure and convert yards to feet before multiplying. +++ More +++ Given that the tank is cylindrical, the 2 yards wide would be the diameter. The Area must be multiplied by the height to find the volume. Area for Diameter is A = Pi x R-squared where Pi is 3.1416 and R is Radius. The Radius is half of the diameter, hence a diameter of 6 ft (2 yds) would have a radius of 3 ft. Use the formula to find the Area: 3.1416 x (3x3) = 3.1416 x 9 = 28.2744 sq ft. Next multiply the area by the height to find the volume: 28.2744 x 15 = 424.116 cu ft. Next multiply the volume by number of gallons per cubic foot (7.481): 424.116 x 7.481 = 3,172.8117 gallons capacity (assuming the dimensions given are inside dimensions).

Find the diameter of the pipe and the pressure and its all simple math after that
Multiply the number of cubic feet in the tank by 7.5 to find gallons.
Outer jaws are used. Inner jaws will be use to find the inner dia of the cylindrical vessel.
V = pi*r^2*L.
