Question

find the capacity in litre of a concial vessel whose diameter is 14cm and slant height is 25cm​

Answer 1

it is a cylinder show its formula equals to 22/7×r^2×h

d=14

so r=d/2=7

h=25

v=22/7 ×7×7×25

=22×7×25

= 3850 cm^3=3850ml

3850/1000=3.85l

Answer 2

Answer:

In a conical vessel,

Diameter=14

Radius=D/2=14/2=7cm

Slant height(l)=25cm

Therefore,Height(h)=√25^2-7^2=24

So,volume=1/3*22/7*r^2*h

=1/3*22/7*7*7*24

=1236cu.cm

=1.23600l
