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
