Question

PLEASE HELP how many times larger is the volume of a cylinder if multiplied by 3

Answer 1

9 times

Explanation:

how many times larger is the volume of a cylinder if the radius is multiplied by 3

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 3

So, the new radius = 3r

And the new volume = π (3r)² h

= π (9r²) h

= 9 π r² h

= 9 the volume of the cylinder of radius r

So, if the radius is multiplied by 3, The volume of the cylinder will be 9 times larger.
