It depends what you know.

The top of a cylinder is in the shape of a circle. So, to find the diameter of the cylinder (which is also the diameter of the circle), if you know the radius, just multiply it by two.

### What is the formula to find the volume for cylinder by using diameter?

The diameter, alone, is not enough to find the volume of a cylinder. You need the height as well. &gt; Where pi = 3.1416, and d = cylinder diameter cylinder volume = pi * (d/2)2 * length of cylinder

### How do you find the diameter of a cylinder?

if u know the t5he radius of the cylinder u can easily find the diameter the formula is d=2r where d =diameter and r=radius

### How do you find the radius of a cylinder if you only have the diameter?

The radius is half the diameter.

### How do you find the diameter of a cylinder without knowing the radius or diameter?

Take the circumference divided by pi to find the diameter and divide the diameter by two to find the radius.

### How do you find the thickness of cylinder?

External diameter minus internal diameter will get you the difference and then you have to divide by two to get the wall thickness. (as the difference in diameter accounts for both sides of the cylinder)

### How do you find diameter of cylinder if pressure at base is given?

You can find the diameter of a cylinder by using the formula for pressure at the base of a cylinder (P = F/A) and the formula for the area of a circle (A = πr^2) where r is the radius of the base. Once you calculate the force acting on the base of the cylinder, you can find the diameter using the formula D = 2r, where D is the diameter.

### How can you find the circumference of a cylinder?

Diameter * pi (3.14159...) = circumfrerence

### How do you find the surface area of a cylinder that has a diameter of 3 in and a height of 6 in?

first you multiply each side by 1,000,000 then you find the surface area of a cylinder that has a diameter of 3in and the height of 6in

### How would you find the diameter?

you measure across the top of the cylinder if it is a cylinder or across the circle if it is flat
