Volume of cylinders
Given the radius and h, the volume of cylinders can be found by using the formula:
Volume
_{cylinder} = Area of base × height = pi × r
^{2}× h and you can
use 3.14 for pi.
Notice that the base of the cylinder is a circle and the formula to get the are is pi × r
^{2}
Example #1:
Calculate Volume
_{cylinder} if r = 2 cm and h = 5 cm
Volume
_{cylinder} = pi × r
^{2}× h
Volume
_{cylinder} = 3.14 × 2
^{2}× 5
Volume
_{cylinder} = 3.14 × 4 × 5
Volume
_{cylinder} = 3.14 × 20
Volume
_{cylinder} = 62.8 cm
^{3}
Example #2:
Calculate Volume
_{cylinder} if r = 4 inches and h = 8 inches
Volume
_{cylinder} = pi × r
^{2}× h
Volume
_{cylinder} = 3.14 × 4
^{2}× 8
Volume
_{cylinder} = 3.14 × 16 × 8
Volume
_{cylinder} = 3.14 × 128
Volume
_{cylinder} = 401.92 inches
