Question

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

`["Assume "pi=22/7]`

 

Answer 1

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.
