Leslie found the volume of a cone having both a height and diameter of 12 inches. Her work is shown below.
1. radius = StartFraction 12 Over 2 EndFraction = 6 inches. 2. base area = pi 6 squared = 36 pi inches squared. 3. cone volume = 36 pi (12) = 432 pi inches cubed.
Analyze Leslie’s work. Is she correct? If not, what was her mistake?
Yes, she is correct.
No, the radius is twice the diameter, so she needed to multiply by two instead of dividing.
No, the value of 62 is 6 times 2, or 12.
No, she forgot to take one-third of the base area times height.
