how much more liquid does a cylindrical tank with a radius 3 ft and ht 12 ft hold than a similar tank with radius 2 ft and ht 10 ft

213.6 ft³

Step-by-step explanation:

The volume (V) of a cylinder = πr²h (r is the radius and h the height)

calculate the volumes of both tanks

V = π * 3² * 12 = 108π ← exact value

V = π * 2² * 10 = 40π ← exact value

difference in volumes = 108π - 40π = 68π ≈ 213.6 ft³ (1 dec. place)
