pi r^2 h is used to determine the volume of a cylinder because when determing the area of a shape you first have to determine the area of the the base of the object and then multiply it by the height. The base of a cylinder is a circle and to find the area of a circle you use pi r^2 and hence the reason why pi r^2 is used to find the volume of the cylinder.

What is the basic formula for volume of a cylinder?
Volume of any prism = area of base x height, so volume of a cylinder = 'pi' x r x r x h, where 'r' is the radius and 'h' is the height, and 'pi' is approximately 3.14.
V equals pi r squared h?
Formula for the volume of a cylinder.
What is the volume and surface of a right circular cylinder?
If the radius is r cm and the height is h cm, then Volume = pi*r^2*h cm^3 and Surface area = 2*pi*r(r+h) cm^2
Formula for the volume of a right circular cylinder?
Pi x r² x h
How do you find the radius of a cylinder?
If you know the height and volume of the cylinder than you can find the radius. You also have to know the formula for volume 'V', which is pi multiplied by both the radius 'r 'squared and the height 'h', or V is equal to pi x r squared x h. The height h is equal to the volume divided by the radius squared and pi.
What is the ratio of volume of a cone to the volume of a cylinder with same ratio?
It is 3:1. This is because volume of a cone is pi/3*r*r*h while vol of a cylinder is pi*r*r*h.
Just tell you the proof that volume of cone is equal to three times the volume of cylinder?
Volume of cylinder = PI r^2 h where r = radius and h= height Volume of Cone = (1/3) PI r^2 h where r=radius and h= height Therefore, the volume of a cone is one-third of the volume of a cylinder.
The radius of a cylinder is four times the height write an equation for the volume of the cylinder as a function of its height?
Volume of a cylinder = PI r^2 h, where r is the radius and h is the height r = 4h (given) Substitute r=4h in the formula Volume = PI (4h)^2 h V = 16 PI h^3
How do you find the ratio of surface area to volume for cylinder?
To find the ratio of surface area to volume for a cylinder, you divide the surface area of the cylinder by its volume. The formula for surface area of a cylinder is 2πrh + 2πr^2, and the formula for the volume of a cylinder is πr^2h. Divide the surface area formula by the volume formula to get the ratio.
Volume of a cylinder into cubic feet?
The volume of a cylinder is pi*r^2*h and, if the radius (r) and height (h) are expressed in feet then the volume is in cubic feet.
What expression represents the volume of a cylinder whose height is equivalent to the length of the radius?
The volume of a cylinder is PI * R2 * H If H is the same as R, then it is PI * R3 (Or PI * H3)
What is the volume of a cylinder?
Volume of a cylinder is pi x radius squared x height. Volume (V) of a cylinder is V=pi*r2*h where r is the radius of the cylinder and h is the height of the cylinder. Value of pi=3.14 (The pi x r2 is the area of a cross section of the cylinder.)
How do you find the radius of half a cylinder when given the volume and height?
from v and h , find r then find r/2. * * * * * That will not work! The formula for the volume of a whole cylinder is V = pi*r2*h So the volume of half a cylinder is V = 1/2*pi*r2*h This give r2 = 2V/(pi*h) and so r = sqrt[2V/(pi*h)]
What is the formula for calculating the volume of a cylinder?
The formula for Cylinder:If we have a cylinder with the radius r, pi is 3.1415, and height h, the volume V of the cylinder is:V = (r squared) (pi) (h)If your radius and height are measured in inches, the volume is in cubic inches.
What is the basic formula for volume of a cylinder?
Volume of any prism = area of base x height, so volume of a cylinder = 'pi' x r x r x h, where 'r' is the radius and 'h' is the height, and 'pi' is approximately 3.14.
What is the formula for the volume of a cylinder?
The volume of a cylinder is simply the area of the circular base times the cylinder's height. Volume of a cylinder = ╥ r² h (pi x radius squared x height) ╥ (Pi) ≈ 3.14 r = radius of the base circle, and h = height of the cylinder --- V= pi r squared times height Volume in cubic units = pi*radius2*height
What the formula of volume for a cylinder?
Pi*r2*h r = radius of circular cross-section h = height of cylinder
