Question

II.

Answer 1

I had this question before, but forgot the answer.

Answer 2

The volume of a cylinder = pi r^2 h
For r=5, v=pi 5^2 3
v=25pi *3
v= 75 pi make sense?

Answer 3

Tes.

Answer 4

Now, if r=10
v= pi 10^2 3
v= pi 100 *3
v=300 pi

Answer 5

What is 300/75?

Answer 6

75

Answer 7

noooo divide 300 by 75

Answer 8

4

Answer 9

Exactly! so if we increased the radius to 10 the volume will be 4x more :)

Answer 10

Thanks.
