Question

if the diameter of a closed cylindrical water storage tank is 14
m and its height is 20 m find the capacity of the tank

Answer 1

In image is your required answer.

Answer 2

Answer: 3080 m²

Step-by-step explanation:

 Diameter of the cylindrical water storage = 14 cm

   ∴   Radius = Diameter ÷ 2

                      = 14 ÷ 2

                      = 7 cm

       Height = 20 m

∴  Capacity of the tank (Volume of the tank) = πr²h

                                                                              = 22/7 × 7 × 7 × 20

                                                                              = 22 × 140

                                                                              = 3080 m²
