Question

An hourglass consists of two sets of congruent composite figures on either end. Each composite figure is made up of a cone and a cylinder:
Hourglass with sand measuring 45 millimeters high
Each cone of the hourglass has a height of 15 millimeters. The total height of the sand within the top portion of the hourglass is 45 millimeters. The radius of both cylinder and cone is 6 millimeters. Sand drips from the top of the hourglass to the bottom at a rate of 10π cubic millimeters per second. How many seconds will it take until all of the sand has dripped to the

Answer 4

very long word problem ! but an easy one :)
read the problem and figure out below :
1) what information we're given
2) what we're asked to find out

Answer 5

made up of a cone and cylinder, 45 mm high, radi of both cylinders 6 mm, and drips 10 π per second

Answer 6

good :) lets find the volume occupied by the sand in top container

Answer 7

the top container looks something like above ?

Answer 8

it is made up of below parts :
1) cone of height 15mm
2) cylinder of height 45-15 = 30mm

Answer 9

yes

Answer 10

we're also given that both cone and cylinder have radius of 6mm
