    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
