Question

what is the volume of this cylinder?
round your answer to the nearest hundredth.
11 m
15 m
cubic meters

Explanation:

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 \(r = 11m\),\(h = 15m\),代入公式可得 \(V=\pi\times11^{2}\times15\)。
先计算 \(11^{2}=121\),则 \(V=\pi\times121\times15\),\(121\times15 = 1815\),所以 \(V = 1815\pi\)。
取 \(\pi\approx3.14159\),则 \(V\approx1815\times3.14159\)。
\(1815\times3.14159=1815\times(3 + 0.14159)=1815\times3+1815\times0.14159\)。
\(1815\times3 = 5445\),\(1815\times0.14159\approx257.086\),\(V\approx5445+257.086 = 5702.086\approx5702.09\)(\(m^{3}\))。

Answer:

\(5702.09\)
