Question
the volume of this cylinder is 17,295.12 cubic meters. what is the height? round your answer to the nearest hundredth. h ≈ meters
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,\(r\)是半径,\(h\)是高。
Step2: 代入已知值求解\(h\)
已知\(V = 17295.12\)立方米,\(r = 18\)米,\(\pi\)取\(3.14\)。
将值代入公式\(17295.12=3.14\times18^{2}\times h\)。
先计算\(18^{2}=324\),则\(17295.12 = 3.14\times324\times h\)。
\(3.14\times324 = 1017.36\),式子变为\(17295.12=1017.36h\)。
那么\(h=\frac{17295.12}{1017.36}\)。
\(h = 17.00\)。
