Answer: the height would be 15

Step-by-step explanation:

v= pi*radius^2*height

1215pi mm= pi*9^2*height

1215pi mm= pi*81*height

(divide by pi on both sides, which isolates pi on both sides)

1215 mm= 81*height

(divide by 81 on both sides, which would isolate 81 on the right side of the equation)

1215/81= 15= height
