Marjorie needs to calculate how much water a cylindrical tank will hold. The tank is 9 feet high and has a diameter of 5 feet. Her work is shown below.
V = pi r squared h
Step 1: V = pi (2.5 squared) (9)
Step 2: V = pi (5) (9)
Step 3: V = (3.14) (5) (9)
Step 4: V = 141.3 cubic feet
What error did Marjorie make when calculating the volume of the tank?
In step 1, she substituted into the volume formula incorrectly.
In step 2, she calculated 2.5 squared incorrectly.
In step 3, the she substituted the wrong amount for Pi.
Marjorie correctly calculated the volume of the cylinder.
