# Solution for Find the capacity in litres of a conical vessel with radius 7 cm, slant height 25 cm - CBSE Class 9 - Mathematics

ConceptVolume of a Right Circular Cone

#### Question

Find the capacity in litres of a conical vessel with radius 7 cm, slant height 25 cm

["Assume "pi=22/7]

#### Solution

Radius (r) of cone = 7 cm

Slant height (l) of cone = 25 cm

"Height (h) of cone "=sqrt(l^2-r^2)

=(sqrt(25^2-7^2))cm

= 24 cm

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

=(1/3xx22/7xx(7)^2xx24)cm^3

= (154 x 8)cm3

= 1232 cm3

Therefore, capacity of the conical vessel

= (1232/1000)litres"           "("1 litre "=1000cm^3)

= 1.232 litres

Is there an error in this question or solution?
