Question
what is the volume of this sphere?
round your answer to the nearest hundredth.
1 in
cubic inches
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\(r = 1\)英寸,将其代入公式可得\(V=\frac{4}{3}\times\pi\times1^{3}\)。
计算\(\frac{4}{3}\times\pi\times1\approx\frac{4}{3}\times3.14159 = 4.18879\)。
Step3: 按要求保留小数
将\(4.18879\)四舍五入到百分位,因为千分位是\(8\)(\(8\gt5\)),所以向百分位进\(1\),得到\(4.19\)。
