In this regard, how do you find the circumference of a base of a cylinder?

To get the circumference, simply multiplytheradius by 2π. So, the circumference can be foundbymultiplying 3 centimeter (1.2 in) by 2π. 3 centimeter (1.2 in)x2π = 18.84 centimeter (7.4 in). Multiplythecircumference of the circle by the height ofthecylinder. This will give you the outer edgesurfacearea.

Furthermore, what is the formula for circumference? Write down the formula for findingthecircumference of a circle using the diameter.Theformula is simply this: C = πd. In thisequation,"C" represents the circumference of thecircle, and "d"represents its diameter. That is to say, you canfind thecircumference of a circle just by multiplying thediameterby pi.

Then, how do you find height of a cylinder?

First, plug the values of the volume, pi, and radiusintothe formula for volume of a cylinder. Last, divide eachsideby 78.5 for the answer, remembering to include the appropriateunitof measurement. The answer is the height ofthecylinder is 10 feet.
