Question

a cylinder has a height of 5 yards and a diameter of 8 yards. what is its volume? round your answer to the nearest hundredth. cubic yards

Explanation:

Step1: 求圆柱底面半径

已知直径\(d = 8\)码，根据半径\(r=\frac{d}{2}\)，可得\(r=\frac{8}{2}=4\)码。

Step2: 代入圆柱体积公式计算

圆柱体积公式\(V=\pi r^{2}h\)，\(h = 5\)码，\(\pi\)取\(3.14\)，则\(V=3.14\times4^{2}\times5\)。
先算\(4^{2}=16\)，再算\(3.14\times16 = 50.24\)，最后\(50.24\times5=251.20\)。

Answer:

\(251.20\)
