Question

what is the volume of this cone?
round your answer to the nearest hundredth.
7 mm
7 mm
cubic millimeters

Explanation:

Step1: 圆锥体积公式

圆锥体积公式为 \( V=\frac{1}{3}\pi r^{2}h \),其中 \( r = 7\) 毫米,\( h = 7\) 毫米。

Step2: 代入数值计算

将 \( r = 7\),\( h = 7\) 代入公式,\( V=\frac{1}{3}\times\pi\times7^{2}\times7=\frac{1}{3}\times\pi\times343\)。

Step3: 计算结果

\( V=\frac{343\pi}{3}\approx\frac{343\times3.14}{3}\approx359.15\)(立方毫米)(\(\pi\)取 \( 3.14\))。

Answer:

\( 359.15\)
