Another Math Problem.

For part A Amy's estimate is inaccurate because when adding fractions they must have the same denominators. Amy probably made the mistake of adding 1/4 and 1/3 without changing the denominators first which gave her 1/7. If she were to do it correctly then she would've ended up with 7/12 as her answer.

My work:

1/4=3/12
1/3=4/12
4/12+3/12=7/12

I hope this helps and if I gave any false information I apologize in advance.

Answer:

314 inches³

Step-by-step explanation:

The area of a cone is πr²h/3. We need to find the height and radius of the cone. The height is 12 inches. radius * 2 = diameter.

Radius * 2 = Diameter
/2                  /2

Radius  = 1/2* Diameter
Radius = 5 inches

We substitute it in:

3.14 * 5² * 12/3:

3.14*25*4

314 inches³
