On July 16, 1882, a massive thunderstorm of Dubuque, Iowa, produced huge hailstones. The diameter of some of the hailstones was 17 inches. Ice weighs about 0.033 pounds/inches cubed. What was the approximate weight of these hailstones to the nearest pound?

Answer 1

Find the volume of the hailstone.

Sphere
Solve for volume
V=4
3πr3

Multiply the volume by 0.033

Answer 2

V=pi/6 D^3
=pi/6 (17)^3
=2572.44in^3 multiply by 0.033
=84.89lb

Answer 3

r = 17/2 = 8.5
V = (4/3)π r^3
= (4/3)π(8.5)^3 = appr 2575.44 inches^3

mass = 2575.44(.033) = 84.89 pounds

seems very unreasonable.
A hailstone with a diameter of 17 inches ? ABsurd
