Question
what is the volume of this cylinder?
3.5 ft.
3 ft.
round your answer to the nearest whole number.
cubic feet
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,\(h\)是圆柱的高。
Step2: 代入数值计算
已知\(r = 3\)英尺,\(h=3.5\)英尺,\(\pi\)取\(3.14\),则\(V = 3.14\times3^{2}\times3.5\)。
先计算\(3^{2}=9\),则\(V=3.14\times9\times3.5\)。
\(3.14\times9 = 28.26\),再计算\(28.26\times3.5=98.91\)。
