1)

Find the volume of cone and the cylinder first.

Volume of Cone: 1/3πr²h 

1/3(3.14)(6)²(15)
565.2

Volume of cylinder = πr²h

(3.14)(6)²(30)
3391.2

Volume of total hourglass = 3391.2 + 565.2 = 3956.4 mm

The time it takes can be found by:

3956.4/10π 
3956.4/31.4
126

So it will take 126 seconds.

2)

Find the volume of the cone and the bubble gum.

volume of cone: 1/3πr²h

1/3(3.14)(1.5)²(3)
7.065

Volume of sphere bubble gum: 4/3πr³
radius = 0.5/2 = 0.25

4/3(3.14)(0.25)³
0.065

Volume of cone filled with ice:

v of cone - v of bubble gum
7.065 - 0.065 = 7

So 7in³ of the cone can be filled with flavored ice.

Hope this helps :)
