Answer:

the volume has grown 25 times

Step-by-step explanation:

the formula to megure (sorry for my bad english) is 1/3 x π x r2 x h

now, this would be 1/3 x π x 4 x 7 = 29,32

if u multiplied the radius and the height by 5, you would get;

1/3 x π x 20 x 35 = 733,03

now to see how much the volume has changed, you devide one on another;

733,03/29,32 = 4/100 = 25

and 25 is 5^2
