The diameter and height of the mug was 10 cm and 15cm respectively. How many minium number of mugs will be required for the barrel to overflow?

Answer 1

Step-by-step explanation:

We know: Volume of cylinder is, V=

here r= radius and h is height;

Volume of Barrel is =

Vol. of Barrel=62800 cm

Now calculating volume of mug=

Given that diameter=10cm {radius is 5cm}=247.27;

Number of mugs will be required for the barrel to overflow >=253.9

Approx 254 mugs of water require to overflow the barrel
