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.
No, a cylinder with radius ( r ) and height ( h ) will not have the same volume as a rectangular prism with side ( r ) and height ( h ). The volume of the cylinder is calculated using the formula ( V = \pi r^2 h ), while the volume of the rectangular prism is ( V = r^2 h ). Since ( \pi ) is approximately 3.14, the cylinder's volume will be greater than that of the rectangular prism.
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.
Formula for the volume of a 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
Pi x r² x h
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.
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
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.
Here, pi = 3.14, r=radius, h=height. Closed cylinder : VOL: pi*r*r*h SA: 2*pi*r*h + 2*pi*r*r (essentially, one "side" of cylinder and top + bottom circles) Open-topped cylinder: VOL: same as above SA: 4*pi*r*h + pi*r*r (two "sides" to cylinder now but only bottom circle remains) Both-ends open cylinder: VOL: same as above (though such a object won't retain anything) SA: 4*pi*r*h (only two "sides" to cylinder)
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.
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.)
The volume of a cylinder is PI * R2 * H If H is the same as R, then it is PI * R3 (Or PI * H3)
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)]
The volume ( V ) of a cylinder can be calculated using the formula ( V = \pi r^2 h ), where ( r ) is the radius of the base and ( h ) is the height of the cylinder. The area of the base is given by ( \pi r^2 ), and multiplying this area by the height ( h ) gives the total volume.
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.
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
Pi*r2*h r = radius of circular cross-section h = height of cylinder
