Explanation:

Step1: 写出圆柱体积公式

圆柱体积公式为 \(V=\pi r^{2}h\)，其中\(r\)是半径，\(h\)是高。

Step2: 代入数值计算

已知\(r = 20\)，\(h = 16\)，代入公式得\(V=\pi\times20^{2}\times16\)。
先计算\(20^{2}=400\)，则\(V=\pi\times400\times16 = 6400\pi\)。
取\(\pi\approx3.1415926\)，则\(V\approx6400\times3.1415926\)。
\(6400\times3.1415926 = 20106.19264\)。

Answer:

\(20106.19\)
