Question:

Find the volume of a milk tank the diameter of whose base is 7 cm and length 14cm .

Answer:

The volume of milk inside the tank is 539 cm³.

Given:

The diameter of the tank is 7 cm.

The length of the tank is 14 cm.

To find:

The volume of the milk inside the tank.

Explanation:

The diameter of the tank is 7 cm.

∴ Radius (r) = (7÷2) cm

                  = 3.5 cm

The length of the tank(h) = 14 cm.

∴ The volume of the tank = (πr²h)

                                           = $(\frac{22 × 3.5^{2} × 14}{7} )$

                                           = (22×3.5×3.5×14)/7

                                            = (22×3.5×3.5×2)

                                            = (22×3.5×7)

                                            = 539 cm³

The volume of the milk = The volume of the tank = 539 cm³.

∴ The volume of the milk inside the tank is 539 cm³.
