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](https://img.qammunity.org/2021/formulas/mathematics/college/t8c1mujun4vn261dtliwrsartk675r5tyx.png)
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](https://img.qammunity.org/2021/formulas/mathematics/high-school/4uvfhqyusvk3k59gfxnj7dcmjhrw67afxe.png)
Taking pi as 3.14:
![\displaystyle V=(1)/(3)3.14\cdot 3^2\cdot 7](https://img.qammunity.org/2021/formulas/mathematics/high-school/mtqhmc1j10qi121ew25jnvsu8iuxgqrvkb.png)
Calculating:
V = 65.9 cubic millimeters
