Question

Meena needs to serve mango juice to her guests in cylindrical tumblers of radius 7 cm up to a height of 10 cm. If she wants to serve 25 guests, how much juice should she prepare?

• A. 35 L
• B. 42.5 L
• C. 38.5 L
• D. 50 L

Answer 1

The correct option is C

38.5 L

We know that,
$Volumeofacylindricalcontainer$
=$\pi$$r^{2}h$

$1000c{m}^3=1L$

Hence, the volume of each cylindrical tumbler
$=\frac{22}{7}\times 7^2\times 10$

$=1540c{m}^3$

So, the total volume of juice required
$=1540\times 25$
$=38500{cm}^3$
= 38.5 L
