Answer:
210 cubic inches
Explanation:
The volume V of a cylinder is given as
V = πr^2h where r is the base radius and h is the height
If two cylinders have the same base, then their radii are the same
Given that one cylinder has a height of 4 inches and a volume of 120 cubic inches then
120 = πr^2 * 4
Divide both sides by 4
30 = πr^2
Given that the second cylinder has a height of 7 inches then the volume
V = πr^2 * 7
Recall that 30 = πr^2
V = 30* 7
= 210 cubic inches
