Answer:

V = 65.9 cubic millimeters

Explanation:

The Volume of a Right Circular Cone

Given a right circular cone of radius r and height h, its volume is calculated as follows:


\displaystyle V=(1)/(3)\pi r^2h

The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:


\displaystyle V=(1)/(3)\pi\cdot 3^2\cdot 7

Taking pi as 3.14:


\displaystyle V=(1)/(3)3.14\cdot 3^2\cdot 7

Calculating:

V = 65.9 cubic millimeters
