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'
Remember the circle eq'n C = pi d Algebraically rearrange d = C/pi Hence C = 12 pi = 3.141592.... ~ 3.1416 Substitute d = 12 / 3.1416 d = 3.8197,,,. ft. The answer!!!!!
Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.(pi= 3.14 or 22 over 7.)
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
diameter = circumference/pi = 12/3.1416 units = 3.62 units (approx)
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm

What does the '12ft 3 in ' represent???? The diameter or the radius???? Please clarify.
38/pi = 12.09577567 or about 12 feet
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
Circumference= 37.68 feet. All you have to do is multiply the diameter by pi. Same with radius. Multiply the radius by two to get the diameter then do diameter times pi.(pi= 3.14 or 22 over 7.)
The circumference of a circle with a diameter of 12 is about: 37.7 (C = diameter x Pi).
The circumference of a 12-foot-diameter circle is 37.7 feet.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
Circumference = 37.7 inches Diameter = 12 inches
diameter = circumference/pi = 12/3.1416 units = 3.62 units (approx)
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
The diameter of a circle with a circumference of 12 is: about 3.82To to this calculation for other circles, just divide the circumference by Pi (about 3.1416). The result is the diameter.
