Step 1 used the wrong formula for a sphere
Step 4 should have taken the cube root instead of dividing by 3
If the volume of a spherical ball is 1437 cubic inches, what is the radius?
Step 1: V=4/3 πr^3
---> Substitute in 1437 for V and solve for r.
Step 2: 1437/π=4/3r^3
---> Divide by π
on both sides
Step 3: 4(1437)/3π =r^3
---> Multiply by 4 and Divide by 3 on both sides
Step 4: 4(1437)/3⋅3π =r
---> Divide by 3 on both sides
