Question

what is formula of daiamerer of cylilender

Answer 1

In case of radius
Diameter of cyclinder=2*r
And in case of volume
Diameter =volume/r^2*h

Answer 2

The diameter, or the distance across a cylinder that passes through the center of the cylinder is 2R (twice the radius). The surface area of an open ended cylinder (as shown) is 2 RL. If the cylinder has caps on the ends, the surface area is 2 RL+2 R. 2. The volume of a cylinder is R2L.
