Question

a cone has a height of 1 yard and a radius of 1 yard. what is its volume? round your answer to the nearest hundredth. cubic yards submit work it out not feeling ready yet? these can help: area of circles lesson: volume of cones

Explanation:

Step1: 写出圆锥体积公式

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

Step2: 代入数值计算

已知\(r = 1\)，\(h = 1\)，代入公式可得\(V=\frac{1}{3}\times\pi\times1^{2}\times1=\frac{\pi}{3}\)。

Step3: 计算并四舍五入

\(\frac{\pi}{3}\approx\frac{3.14159}{3}\approx1.05\)（保留两位小数）

Answer:

\(1.05\)
