Answer: Third red dot after 30 on the number line represents the approximate volume of a cone.
Step-by-step explanation:
Since we have have given that
Radius of cone = 3 units
Height of cone = 4 units
So, Volume of cone is given by
[tex]Volume=\frac{1}{3}\pi^2\times h\\\\Volume=\frac{1}{3}\times 3.14\times 3\times 3\times 4\\\\Volume=37.68\ units^3[/tex]
Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.
