Question
what is the volume of this sphere? round your answer to the nearest hundredth. 12 mm cubic millimeters
Step1: 写出球体体积公式
球体体积公式为\(V = \frac{4}{3}\pi r^{3}\),其中\(r\)为半径。
Step2: 代入半径值计算
已知半径\(r = 12\)毫米,将其代入公式可得:
\(V=\frac{4}{3}\times\pi\times12^{3}\)
先计算\(12^{3}=12\times12\times12 = 1728\),则\(V=\frac{4}{3}\times\pi\times1728\)。
\(\frac{4}{3}\times1728 = 4\times576=2304\),所以\(V = 2304\pi\)。
取\(\pi\approx3.14159\),则\(V\approx2304\times3.14159\)。
\(2304\times3.14159 = 7238.22936\)。
