Question

Cylinder A has a radius of 7 inches and a height of 5 inches. Cylinder B has a volume of 490π. What is the percentage change in volume from cylinder A to cylinder B? 50% decrease 75% increase 150% decrease 100% increase

Answer 1

The percentage change in volume between cylinder A and cylinder B is 50% Step-by-step explanation:

Explanation:

The volume of a cylinder is given by the formula

V= πr^2h

For cylinder A, where r = 7 and h = 5 , pi = 22/7

V= π *7^2 * 5

V= π * 49 * 5

V = 769.69 cubic inch

For cylinder B

V = 490Pi

V = 153 cubic inch

The percentage change in volume between cylinder A and cylinder B

=[ (VA-VB)/VB] *100

=(1539.3804-769.69)/1539.3804

= 0.5000 100

= 50%
