Question

A hummingbird eyeball has a diameter of approximately 0.6 cm. Identify how many times as great is the volume of a human eyeball as the volume of a hummingbird eyeball?

Answer 1

First you need the diameter, 0.6/2 because you need the radius to do the equation! 

So 0.6/2 = 0.3

So now 4/3*π*0.3^3 (To the 3rd power)

So that equals 0.11!!
