If the volume of a spherical ball is 1437 cubic inches, what is the radius?
Step 1: V = 4/3 * pi * r ^ 3 ---> Substitute in 1437 for V and solve for r.
Step 2: 1437/pi = 4/3 * r ^ 3 ---> Divide by pi on both sides
Step 3: sides (4(1437))/(3pi) = r ^ 3 ---> Multiply by 4 and Divide by 3 on both
Step 4: (4(1437))/(3*3pi) = r ---> Divide by 3 on both sides

Step 1 used the wrong formula for a sphere
Step 2 should have multiplied by on both sides
Step 3 should have multiplied by 3 and divided by 4 on both sides
Step 4 should have taken the cube root instead of dividing by 3
Step 4 should have taken the square root instead of dividing by 3
Step 3 should have multiplied by 3 and divided by 4 on both sides
Step 4 should have taken the cube root instead of dividing by 3
