Question
what is the volume of this sphere?
round your answer to the nearest hundredth.
6.1 mm
cubic
millimeters
Step1: 明确球体体积公式
球体体积公式为 \( V=\frac{4}{3}\pi r^{3}\),其中 \(r\) 为球体半径。
Step2: 代入半径计算
已知半径 \(r = 6.1\) \(mm\),将其代入公式可得:
\(V=\frac{4}{3}\times\pi\times(6.1)^{3}\)
先计算\((6.1)^{3}=6.1\times6.1\times6.1 = 226.981\)
再计算\(\frac{4}{3}\times\pi\times226.981\approx\frac{4}{3}\times3.14\times226.981\)
\(\frac{4}{3}\times3.14\times226.981=\frac{12.56}{3}\times226.981\approx4.1867\times226.981\approx948.01\)(\(mm^{3}\))
