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

Answer:

42.39 $cm^{2}$

Step-by-step explanation:

cone formula: $V =\frac{1}{3} \pi r^{2} h$

diameter to radius

9 cm to 4.5

1.) $V = \frac{1}{3} \pi (4.5^{2}) (6)$

2.) $= \frac{1}{3}\pi (20.25)(6)$

3.) $= \frac{1}{3} 121.5\pi$

4.) divide 121.5 by 3

$= 13.5\pi$

5.) multiply by 3.14

V = 42.39
