Question
what is the volume of this sphere? round your answer to the nearest hundredth. 2 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\(r = 2\)毫米,将其代入公式可得\(V=\frac{4}{3}\times\pi\times2^{3}\)。
先计算\(2^{3}=8\),则\(V=\frac{4}{3}\times\pi\times8=\frac{32\pi}{3}\)。
取\(\pi\approx3.14\),则\(V=\frac{32\times3.14}{3}=\frac{100.48}{3}\approx33.49\)(立方毫米)。
