Answer:

r = 5

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

Here V = 625π, h = 25, thus

πr² × 25 = 625π  ( divide both sides by π )

25r² = 625 ( divide both sides by 25 )

r² = 25 ( take the square root of both sides )

r = [tex]\sqrt{25}[/tex] = 5
