the question: a cylindrical tank has a circumference of 13.2, determine the diameter and the cross-sectional area of the tank?
Convert the degrees to radians. Also, you need the radius, not the diameter. In that case, the distance along the circle is simply the product of the angle, and the radius.

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.

I am going to assume you have a cylindrical tank. The base of a cylindical tank is a circle. The circumference of a circle is 2*Pi*r or Pi*d. So, the circumference of your tank would be Pi*12 ~= 37.7'
circumference = 42*pi = 131.947 feet and rounded to 3 decimal places
Impossible to answer ! Even given the capacity and the height - there are still more than one answer !

None it is only 2D or flat
First find the surface area of the side of the tank, which is just:Pi*diameter*height = 3.14*14 ft * 12 ft = 527.52 ft2Next find the area of the bottom of the tank, which is just the area of a circle:Pi/4 * (diameter)2 = 3.14/4*(14 ft)2 = 153.86 ft2Add the two up and you'll need approximately 682 ft2 of material to construct the tank.

To solve this we need to find the area of the tank in cubic feet, and then convert that to gallons. The volume of a cylinder can be found by multiplying the area of its base by its height. The area of a circle is equal to Pi×r2, where r is the radius of the circle. The radius is half of the diameter, so the area of the base of the tank if Pi×12, which equals Pi. Multiply this by 5 to find that the volume of the tank is 5 Pi cubic feet. Convert this to gallons to find that the volume is 117.5 gallons.
If it's really 4 ft around then the circumference is 4 ft. English is not your first language, then?
The length of the tank is 60", the width of the tank is 27" and the height of the tank is 44" respectively. How many gallons of oil will the tank hold?
