Question

A cylindrical jar of height 'H' and radius 'R' is used to fill water in a cone of same height and radius. How many conical jars can it fill?

• A. 2
• B. 3
• C. 6
• D. 9

Answer 1

The correct option is B

3

Volume of cylinder having height 'H' and radius 'R' = $\pi (R{)}^{2}H$

Volume of cone having same height 'H' and radius 'R' = $\frac{1}{3}\pi (R{)}^{2}H$

So, we can see that for same radius and height, the volume of a cylinder is thrice that of a cone. So, it can fill 3 conical jars.
