The sum of percentage radius of cone A, Cone B, cylinder A and Cylinder B is 100 and distribution of this sum between all four figures is 10%, 20%, 40% and 30%. If the height of cone B is 15 and cylinder A is 10, then find by what percentage the volume of cylinder A is more than cone B.

The sum of percentage radius of cone A, Cone B, cylinder A and Cylinder B is 100 and distribution of this sum between all four figures is 10%, 20%, 40% and 30%. If the height of cone B is 15 and cylinder A is 10, then find by what percentage the volume of cylinder A is more than cone B. Correct Answer 700%

Volume of cone B

⇒ (20% of 100)2 × 15 × π/3

⇒ 20 × 20 × 15× π/3

⇒ 2000π

Volume of cylinder A

⇒ (40% of 100)2 × 10 × π = 16000π

Required %

⇒ (16000π - 2000π)/2000π × 100 = 700%
