Question

a cylinder has a height of 15 yards and a diameter of 22 yards. what is its volume? round your answer to the nearest hundredth. cubic yards

Explanation:

Step1: 计算半径

已知直径\(d = 22\)码，根据半径\(r=\frac{d}{2}\)，可得\(r=\frac{22}{2}=11\)码。

Step2: 代入圆柱体积公式

圆柱体积公式\(V=\pi r^{2}h\)，\(\pi\)取\(3.14\)，\(h = 15\)码，\(r = 11\)码，代入可得\(V=3.14\times11^{2}\times15\)。
先计算\(11^{2}=121\)，则\(V=3.14\times121\times15\)。
再计算\(3.14\times121 = 379.94\)，则\(V=379.94\times15\)。
最后\(379.94\times15=5699.1\)（立方码）。

Answer:

\(5699.10\)
