Question

What is the radius of a cone with diameter​ d? An ice cream cone is filled exactly level with the top of the cone. The cone has a 9​-cm diameter and 6​-cm depth. Approximate how much ice cream​ (in cm cubed​) is in the​ cone? Use 3.14 for pi.

Answer 1

42.39

Explanation:

Answer 2

42.39
`cm^(2)`

Explanation:

cone formula:
`V =(1)/(3) \pi r^(2) h`

diameter to radius

9 cm to 4.5

1.)
`V = (1)/(3) \pi (4.5^(2)) (6)`

2.)
`= (1)/(3)\pi (20.25)(6)`

3.)
`= (1)/(3) 121.5\pi`

4.) divide 121.5 by 3

`= 13.5\pi`

5.) multiply by 3.14

V = 42.39
