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.
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.
244.78 gallons
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
To calculate the diameter of a cylindrical oil tank, you can use the formula: diameter = 2 * square root of (volume / (pi * height)), where the volume and height of the tank are known. Input these values into the formula to find the diameter.
Impossible to answer ! Even given the capacity and the height - there are still more than one answer !
Bye holding it

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?
