Question
the volume of this cylinder is 6,838.92 cubic inches. what is the height? round your answer to the nearest hundredth. 11 in h h ≈ inches
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
已知 \(V = 6838.92\) 立方英寸,\(r = 11\) 英寸,\(\pi\) 取 \(3.14\),则 \(6838.92=3.14\times11^{2}\times h\)。
先计算 \(11^{2}=121\),式子变为 \(6838.92 = 3.14\times121\times h\)。
再计算 \(3.14\times121 = 379.94\),式子变为 \(6838.92=379.94h\)。
Step3: 求解 \(h\)
\(h=\frac{6838.92}{379.94}\),\(h = 18.00\)。
