Question
what is the volume of this cylinder?
round your answer to the nearest hundredth.
8 m
7 m
cubic meters
Step1: 写出圆柱体积公式
圆柱体积公式为\(V = \pi r^{2}h\)(\(r\)为底面半径,\(h\)为高)。
Step2: 代入数值计算
已知\(r = 8m\),\(h = 7m\),\(\pi\)取\(3.14\),则\(V=3.14\times8^{2}\times7\)。
先计算\(8^{2}=64\),再计算\(3.14\times64 = 200.96\),最后计算\(200.96\times7=1406.72\)。
