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 )

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

4.5%
