If the height of a cylinder is multiplied by four, how will it affect its volume ?

Answer 1

The formula for the volume of a cylinder is:

V = π r² h

If the height is multiplied by 4, this means the new height is 4h. Substituting this into the equation we get:

V = π r² (4h)

rewriting we get:

V = 4π r² h

The only difference between this formula and the orginal volume formula is that it is multiplied by 4.

Therefore, the volume with be 4 times the volume of the original cylinder if the height is multiplied by 4.

Hope this helps!
