Question
what is the volume of this cylinder?
round your answer to the nearest hundredth.
18 ft
7 ft
cubic feet
Step1: 计算圆柱底面半径
已知圆柱底面直径\(d = 18\)英尺,根据半径\(r=\frac{d}{2}\),可得\(r=\frac{18}{2}=9\)英尺。
Step2: 计算圆柱底面积
根据圆的面积公式\(S=\pi r^{2}\),\(\pi\)取\(3.14\),则\(S = 3.14\times9^{2}=3.14\times81 = 254.34\)平方英尺。
Step3: 计算圆柱体积
根据圆柱体积公式\(V=Sh\)(\(h\)为圆柱的高),已知\(h = 7\)英尺,所以\(V=254.34\times7=1780.38\)立方英尺。
