Question
what is the volume of this cylinder?
round your answer to the nearest hundredth.
11 in
11 in
cubic inches
Step1: 写出圆柱体积公式
圆柱体积公式为 \(V=\pi r^{2}h\),其中 \(r\) 是底面半径,\(h\) 是高。
Step2: 代入数值计算
已知 \(r = 11\) 英寸,\(h = 11\) 英寸,\(\pi\) 取 \(3.14\),则 \(V=3.14\times11^{2}\times11\)。
先计算 \(11^{2}=121\),则 \(V = 3.14\times121\times11\)。
再计算 \(3.14\times121 = 379.94\),则 \(V=379.94\times11\)。
最后 \(379.94\times11 = 4179.34\)(立方英寸)。
