Question

Height of a cylindrical barrel is 50 cm and radius of its base is 20 cm. Anurag started to fill the barrel with water, when it was empty, by cylindrical mug. The diameter and height of the mug was 10 cm and 15 cm respectively. How many minimum number of mugs will be required for the barrel to overflow.

Answer 1

Answer:

34

Step-by-step explanation:

• volume of barrel= 157000 cm cube

• volume of mug= 4712.39 cm cube

• number of mugs required to overflow the barrel

      = (volume of barrel \ volume of mug) +1*

      = (157000/4712.39)+1

      = (33**)+1

      =34

Note:  

* +1 because, (volume of barrel \ volume of mug) will give the number of mugs required to fill the cylinder but we need to overflow it. therefore,+1

**  approxed value because the quotient obtained id irrational
