The volume of a cone of radius r and height h is given by:
[tex]V=\frac{\pi r^2h}{3}[/tex]
The cone in the figure has a radius of r = 2.1 cm and a height of h = 6.2 cm.
Substituting:
[tex]V=\frac{\pi\times\lparen2.1cm)^2\times6.2\text{ cm}}{3}[/tex]
Using the value 3.14 for pi and calculating:
V = 28.62 cm 3
You should write 28.62 in the first box and 3 in the second box (for cubic cm)
