Question

A milk tank is in the form of a
cylinder whose radius is 1.5m
and height is 10.5m.Find the
quantity of milk in litres that
can be stored in the tank.

Answer 1

Information provided to us:
Radius of the tank, r = 1.5 m
Height of the tank, h = 10.5 m

We know that the quantity of milk that can be stored in the tank will be equal to it's volume of the cylinder and we know that the volume of a cylinder related as follows:
Volume of cylinder = π * r ^ 2 * h

Hence substituting the values in the above discussed formula,

Volume, V = π * ( 1.5 ) ^ 2 * 10.5
V = ( 22 / 7 ) * 2.25 * 10.5
V = 22 * 2.25 * 1.5
V = 22 * 3.375
V = 74.25 cu. m

We know that, one cu. metre is equal to one thousand litres.

So,

V = 74.25 * 1000
V = 74250 l

Hence,

The quantity of milk that can be stored in the tank = 74250 l

Answer 2

hey mate!

Quantity of water, means it's capacity or volume.

A milk tank is in the form of a
cylinder whose radius is 1.5m
and height is 10.5m.Find the
quantity of milk in litres that
can be stored in the tank.*

Volume of cylinder = pi*r² *h

= 22/7 * (1.5)² * 10.5 m³

= 22/7 * 2.25* 10.5 m³

= 74.25 m³

Since 1 m³ = 1kL

= 74.25kL = 74250 L.

Hope it helps you!
