Question

A cylinder drum of radius 2.1 m and height 2.8 m full of grain. The grain is emptied into a large drum of radius 3.5 m. Find the level of the grain in the new drum.

Answer 1

Answer:

1.008 m

Step-by-step explanation:

volume of the first drum =π*2.1*2.1*2.8

vol. of first drum= vol.of second drum

therefore π * 2.1 *2.1*2.8= π* 3.5 *3.5* h

therefore h = (2.1*2.1*2.8)/(3.5*3.5)

h = 1.008 m

therefore the level of grain in new drum is 1.008 m
