An ostrich egg has about the same volume of a sphere with a diameter of 5in. If the eggshell is about 1/12 in thick, find the volume of just the shell, not including the interior of the egg. Round your answer to the nearest tenth and use 3.14 for pi.

Respuesta :

V = (4/3)*pi*r^3
so....
V = (4/3)*pi*(2.5)^3 - (4/3)*pi*(2.46)^3
V = 65.449846958 - 62.358251704
V = 3.091595254
when you round this you get the volume of the eggshell to be 3.09 cubic inches
