Answer:
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.
