Multiple choice

A milk tank is in the form of cylinder whose radius is $1.5\;m$ and length is $7\;m$. Find the quantity of milk in litres that can be stored in the tank?

  1. $49500\;litres$
  2. $48500\;litres$
  3. $79500\;miliitres$

  4. None of these

A Correct answer
Explanation

The tank's volume is pi × (1.5)^2 × 7 = 15.75pi cubic metres. Using pi = 22/7 gives 49.5 cubic metres, and 1 cubic metre equals 1000 litres. Hence, the capacity is 49,500 litres.

AI explanation

To find the quantity of milk, calculate the volume of the cylinder using the formula pi times r squared times h, which is 22 over 7 times 1.5 times 1.5 times 7. This gives 49.5 cubic meters, and since 1 cubic meter equals 1000 litres, the total quantity is 49500 litres.
