Question

A glass is in the shape of cylinder of radius 7 cm and height 10 cm. Find the volume of juice in litres required to fill 6 such glasses.

Answer 1

r =7cm
h = 10cm
volume of the cylinder=$\pi$$r^{2}$*h
=22/7*$7^{2}$*10
=1540$cm^{3}$
The volume of juice in litres required to fill 6 glasses= 1540*6=9240$cm^{3}$
=9240/1000=9.24l

Answer 2

Given:

Radius=7cm

Height=10cm

To find:

The volume of 6 such glasses

Solution:

The required volume is 9,240 $cm^{3}$.

We can obtain the total required volume by multiplying one glass's quantity with 6.

The glass's volume=π$r^{2}$h, r=radius and h=height.

Using the values, we get

=22/7×7×7×10

=22×70

=1,540 $cm^{3}$

Now, the volume of 6 glasses=volume of one glass×6

=1540×6

=9,240 $cm^{3}$

Therefore, the required volume is 9,240 $cm^{3}$.
