Question

______PLEASE ANSWER______how many times larger is the volume of a cylinder if the radius is multiplied by 5

Answer 1

25 times

Explanation:

Let the radius of the cylinder is r and the height is h

So, the volume of the cylinder is π r² h

If the radius is multiplied by 5

So, the new radius = 5r

And the new volume = π (5r)² h

= π (25r²) h

= 25 π r² h

= 25 the volume of the cylinder of radius r

So, if the radius is multiplied by 5, The volume of the cylinder will be 25 times larger.
