the question: a cylindrical tank has a circumference of 13.2, determine the diameter and the cross-sectional area of the tank?
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'
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.
245 feet.
Roughly 317.5 feet squared.
35 cubic feet
Volume of a cylindrical tank 8 feet in diameter and 8 feet tall is pi x 16 square feet (radius squared) x 8 feet (height) = 402 cubic feet.
A cylindrical tank will be approximately 8 feet wide and 12 feet high.
Length 40 feet x diameter 11.4 feet what is the thickness of the tank body?
Approx. 408.4 feet.
Its total surface area is 15614 square feet.
