Question

A glass is in the shape of a cylinder of radius 7 cm and height 10 cm. Find the volume of juice in litres required to fill 4 such glasses.

• A. 5 litres
• B. 6.62 litres
• C. 6.16 litres
• D. 10 litres

Answer 1

The correct option is C

6.16 litres

Radius of the glass = 7cm

Height of the glass = 10 cm

Volume of 1 glass =$\pi r^{2}h$

$=\frac{22}{7}\times 7\times 7\times 10$

$=1540c{m}^3$

Volume of juice to fill 4 such glasses

= $4\times 1540$

$=6160c{m}^3$

Volume in litres = $\frac{6160}{1000}$=6.16 litres.
