Answer:

405π

Explanation:

Use the formula for Volume Of Cylinder (V=πr²h) where "V" represents the volume, "r" represents the radius, and "h" represents the height

The volume and the radius are given. (V=45π, r=3)

1. Solve for height

V=πr²h

45π=π3²h

45π/π=3²h

45=3²h

45=9h

45/9=h

h=5

2. Plug the new radius (3*3=9) into this formula and solve for "V"

V=π9²5

V=π81*5

V=405π

NEW VOLUME AFTER A TRIPLED RADIUS IS 405π
