Question

find capacity of a cylinder in litre with radius 7 cm and height 30 cm

Answer 1

volume of cylinder=pi r^{2} h
v=$\frac{22}{7}$ x 7x7x30
v=22x7x30
v=154x30
v=4620cm cube
caoacity in litres= 4620/1000=4.62L

Answer 2

Hey friend here is ur ans ,

Given : r = 7cm
h = 30cm
Volume of Cylinder = πr^2h
= 22/7× 7×7×30  
=22 × 7 ×30
= 4620 cm^3

As we got volume ofpr capacity in cm^3
to convert in litres ( 1 cm^3 = 0.001 litre )

so, divide 4620 by 1000 = 4.620 litre or 4.62 litre
Thus , this is ur ans in litre .
