Question

bonnie measured a cylinder with a radius of 7 centimeters and a height of 3 centimeters. what is the volume, in cubic centimeters, of the cylinder? 441π 462π 147π 49π

Explanation:

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\(r = 7\)厘米,\(h = 3\)厘米,代入公式得\(V=\pi\times7^{2}\times3\)。
先计算\(7^{2}=49\),再计算\(49\times3 = 147\),所以\(V = 147\pi\)。

Answer:

\(147\pi\)(对应选项:\(147\pi\))
