Question

what is the volume of this cone?
round your answer to the nearest hundredth.
5 yd
4 yd
cubic yards

Explanation:

Step1: 计算圆锥底面半径

已知圆锥底面直径\(d = 4\)码，根据半径\(r=\frac{d}{2}\)，可得\(r=\frac{4}{2}=2\)码。

Step2: 代入圆锥体积公式计算

圆锥体积公式为\(V=\frac{1}{3}\pi r^{2}h\)，其中\(r = 2\)码，\(h = 5\)码，\(\pi\)取\(3.14\)。
则\(V=\frac{1}{3}\times3.14\times2^{2}\times5\)
\(=\frac{1}{3}\times3.14\times4\times5\)
\(=\frac{1}{3}\times62.8\)
\(\approx20.93\)（立方码）

Answer:

\(20.93\)
