1st day: 1 1/2 hours
2nd day: half of first day = 1/2 * 1 1/2 hours
3rd day: 2 1/2 times as long as first day: 2 1/2 * 1 1/2 hours
1 1/2 + 1/2 * 1 1/2 + 2 1/2 * 1 1/2 =
= 3/2 + 1/2 * 3/2 + 5/2 * 3/2
= 3/2 + 3/4 + 15/4
= 6/4 + 3/4 + 15/4
= 24/4
= 6

Answer:
im am confused sorry guys.
V = 4/3 (pi) r^3
ball with radius of 18 cm...
V = 4/3(3.14)(18^3)
V = 4/3(3.14)(5832)
V = 24429.02
ball with radius of 12...
V = 4/3(3.14)(12^3)
V = 4/3(3.14)(1728)
V = 7238.23
24429.02 - 7238.23 = 17190.79 greater <====
