Question

the volume of this cylinder is 3,918.72 cubic meters. what is the height?
round your answer to the nearest hundredth.
8 m
h
h ≈ meters

Explanation:

Step1: 写出圆柱体积公式

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

Step2: 代入已知值求解\(h\)

已知 \(V = 3918.72\) 立方米,\(r = 8\) 米,\(\pi\)取 \(3.14\)。
将值代入公式 \(3918.72=3.14\times8^{2}\times h\)。
先计算 \(8^{2}=64\),则 \(3918.72 = 3.14\times64\times h\)。
\(3.14\times64 = 200.96\),式子变为 \(3918.72=200.96h\)。
两边同时除以 \(200.96\),\(h=\frac{3918.72}{200.96}\)。
\(h = 19.5\)。

Answer:

\(19.50\)
