circumference = 42*pi = 131.947 feet and rounded to 3 decimal places
the question: a cylindrical tank has a circumference of 13.2, determine the diameter and the cross-sectional area of the tank?
To determine the number of rafters needed for a 40-foot diameter tank with a chord distance of 6' 3 18" (which is 6.25 feet), you first calculate the circumference of the tank using the formula (C = \pi \times D), where (D) is the diameter. For a 40-foot diameter tank, the circumference is approximately 125.66 feet. Dividing the circumference by the chord distance (6.25 feet) gives you about 20 rafters needed to evenly space them around 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'
To calculate the circumference of a round tank, use the formula ( C = 2\pi r ), where ( C ) is the circumference and ( r ) is the radius of the tank. Alternatively, if you know the diameter ( d ), you can use the formula ( C = \pi d ). Make sure to use the value of ( \pi ) (approximately 3.14 or 22/7) to get the circumference in the desired units.
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.
Approx. 408.4 feet.
Length 40 feet x diameter 11.4 feet what is the thickness of the tank body?
