Answer:
result = 15cm
Explanation:
Hi! to can solve this, we have to keep in mind this formulas:
1) Area of a circuference:
A1 = π
; where r = radius
2) Area of a cylinder:
A2 = (π
) * (h) ; where h= height
now we solve:
first, we have to calculate the area of the circumference
A1 =
=
then, we already know the volume of the cylinder, and the area of the circumference, so we have to find just h of the second formula:
A2 = (π
) * (h)
=
* (h)
= h
h = 15cm
