Answer:
42.39 [tex]cm^{2}[/tex]
Step-by-step explanation:
cone formula: [tex]V =\frac{1}{3} \pi r^{2} h[/tex]
diameter to radius
9 cm to 4.5
1.) [tex]V = \frac{1}{3} \pi (4.5^{2}) (6)[/tex]
2.) [tex]= \frac{1}{3}\pi (20.25)(6)[/tex]
3.) [tex]= \frac{1}{3} 121.5\pi[/tex]
4.) divide 121.5 by 3
[tex]= 13.5\pi[/tex]
5.) multiply by 3.14
V = 42.39
