Answer:

Step-by-step explanation:

Volume of a Cylinder : V=πr2h

Substitute what you know:

25 = π1.5(2)h

Solve what you know:

25 = π3h

25 = 9.42h

Inverse Operation: (Divide both sides)

25 / 9.42  =  9.42 / 9.42 h

Cancel out the right side but leave the variable

25/9.42 = h

Solve:

2.65 = h

Check:

Volume of a Cylinder :

V = πr2h

V = π1.5 (2) 2.65

Multiply:

V = 4.71 (2) 1.65

V = 9.42 (2.65)

V = 24.96

Round/Estimate:

24.96 - 25
