Question

alec is finding the volume of two cones. the smaller cone has a radius of 8 inches and a height of 3 inches. the larger cone has the same radius but a height of 6 inches. what is the volume, in cubic inches, of the smaller cone? 201π 21π 64π 85π

Explanation:

Step1: 写出圆锥体积公式

圆锥体积公式为\(V = \frac{1}{3}\pi r^{2}h\)（\(r\)是底面半径，\(h\)是高）。

Step2: 代入小圆锥数据计算

已知小圆锥半径\(r = 8\)英寸，高\(h = 3\)英寸，代入公式得\(V=\frac{1}{3}\pi\times8^{2}\times3\)。
先计算\(8^{2}=64\)，再计算\(\frac{1}{3}\times3 = 1\)，则\(V = 64\pi\)。

Answer:

\(64\pi\)
