In step 2, V = show the error in volume work.
Solution:
Given data:
The steps shows it is sphere.
Radius of the sphere = 12.5
The value of π = 3.14
Volume of the sphere =
Step 1:
Step 2:
Step 3:
Step 4:
V = 8177.08 cubic units
This is the correct solution.
But in the given options, in step 2, 12.5 is multiplied by 3.
That is not the correct step. You have to do 12.5 × 12.5 × 12.5.
Hence in step 2, V = show the error in volume work.
Remember that when you find 30% of the number you have to subtract the 30% from your original $90 because it is 30% off the original price.
