# Find the volume of the right circular cone with radius 3.5 cm, height 12 cm - Mathematics

Find the volume of the right circular cone with radius 3.5 cm, height 12 cm

["Assume "pi=22/7]

#### Solution

Radius (r) of cone = 3.5 cm

Height (h) of cone = 12 cm

"Volume of cone "=1/3pir^2h

=[1/3xx22/7xx(3.5)^2xx12]cm^3

=(1/3xx22xx1/2xx3.5xx12)cm^3

= 154 cm3

Therefore, the volume of the cone is 154 cm3.
