27) a cone with diameter 2 mi and a height of 3
mi.

3.14 mi^3

Step-by-step explanation:

Before you do the question, you need to know that we need to divide 2 to the diameter. Because the circle  volume don't need it.

So we can get the bottom circle area: 1^2 * 3.14 = 3.14

And we need to times the height of the cone: 3.14*3 = 9.42

And divide by 3. 9.42/3=3.14

That's it, you got the answer.
