The volume of a cone is 164 pi cubic feet. Its height is 12 feet. Ashlyn is finding the area of the base of the cone. Her work is shown below.

V = one-third B h. Step 1: 164 pi = one-third pi B (12). Step 2: 164 pi = 4 pi B. Step 3: StartFraction 164 pi Over 4 pi EndFraction = B. Step 4: 41 = B.

What is Ashlyn’s error?
In step 3, Ashlyn did not subtract 4 pi from 164 pi.
In step 2, Ashlyn did not find the correct value for multiplying One-third and 12.
In step 1, Ashlyn included a factor of Pi on the right side of the formula.
In step 1, Ashlyn did not substitute the correct value for the height in the formula.
