Calculating the Volume of a Cylinder

1. Find the radius of the circular base.
2. Calculate the area of the circular base.
3. Find the height of the cylinder.
4. Multiply the area of the base by the height.

Assuming you are correct that the radius is 2' 6" and not the diameter.
Convert the inches to centimetres
1" = 2.54 Cms
Radius = 2' 6" = 30" X 2.54 = 76.2 Cms
Height = 5' 2" = 62" X 2.54 = 157.48 Cms
Volume of cylinder = Pi x radius squared x height
3.142 x 76.2 x 76.2 x 157.48 = 2,873,038.9 cc
Divide by 1000 to find how many litres (interest note 1000cc car engine is 1 litre)
2,873,039 cc / 1000 = 2,873 litres

The radius or the volume of the space?

Volume of right cylinder is
V=(Area of base)*height.
If cylinder is circular Area of base =PI*radius^2=Pi*r^2
Volume is V=Pi*(8^2)*6 cm^2
Finish the calculation.

Volume of a right circular cylinder of radius r and height h is
V=PI*(r^2)*h
Figure out which is the radius and which is the height, then plug in the formula above. Result is in cm^3

Since the radius and height are positive quantities, the volume will also be positive. First quadrant of the (r, V) plane.

V = (pi)(r square)(h) V= Volume (the amount we need to calculate)
pi = 3.14...
r = radius of cylinder (remember this is half that of the circumference)
h = height of cylinder

To make it easier for you below are the figures for the Cylinder.
Radius= 11.5 inches
Height = 17 inches.
Now use the formula above to calculate it.

For the Jelly Bean its,
Radius = 0.25 inches
Height = 0.5
Use the same formula above for jelly bean as well.


Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly

AND VOILA, you have the amount of jelly beans in a jar (Round the figure out)

Cheers!

About 503 liters or 0.503 cubic meters.
If this is homework, be sure to show your work.

Is this a right circular cone or a right circular cylinder?
Volume of cylinder= Pi*(r^2)*h
Volume of cone is 1/3 of volume of cylinder with same height and radius.
Solve for h
h=(Volume)/(PI*r^2) for cylinder
