Which point on the number line represents the approximate volume of a cone with the radius of 3 units and a height of 4 units? U

alekssr [168]

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

$Volume=\frac{1}{3}\pi^2\times h\\\\Volume=\frac{1}{3}\times 3.14\times 3\times 3\times 4\\\\Volume=37.68\ units^3$

Hence, Third red dot after 30 on the number line represents the approximate volume of a cone.
