an ostrich egg has about the same volume as a sphere with a diameter of 5 inches. if the eggshell is about 1/12 inch thick, find the volume of just the shell, not including the interior of the egg. explain how you got your answer. round your answer to the nearest tenth.

Volume of a sphere is
v=4/3 times pi times radius^3
to solve, find the volume of:
a. total egg
b. interior
then subtract b from a and get answer

so
aprox pi to 3.14
v=4/3 times 3.14 times r^3

diameter=2radius
radius=1/2diameter
diameter=5
radius=1/2 of 5
radius=2.5

solve for a.
radius=2.5
subsitute
4/3 times 3.14 times 2.5^3
4/3 times 3.14 times 15.625
65.4167=a

solve for b
radius is only on 1 side so
2.5-1/12=30/12-1/12=29/12=2.4166
subsitute
v=4/3 times 3.14 times 2.4166^3
4/3 times 3.14 times 14.114
59.0906=b

a=65.4167
b=59.0906
a-b=65.4167-59.0906=6.326
tenth is regarding up to the 2nd decimal place
6.32
2<5
6.3 cubic inches or 6.3in^3

answer is 6.3 in^3
