半径35毫米的球体体积是多少
\u534a\u5f84\u662f2.35\u7684\u7403\u7684\u4f53\u79ef\u662f\uff1f\u534a\u5f84\u662f2.35\u00f72=1.175\u7c73
4/3*3.14*1.175*1.175*1.175=6.8
\u6240\u4ee5\u4f53\u79ef\u662f6.8\u7acb\u65b9\u7c73
\u7403\u7684\u4f53\u79ef\u516c\u5f0f\u662fV=4/3\u03c0R^3
可以，球体积公式V=4πR^3/3=4*3.1416*35^3/3=179594mm^3v=(4/3)*3.14r*r*r
179594mm^3
球体积计算公式：V=4*π*r*r*r/3，如果π=3.14的话，V=4*3.14*0.035*0.035*0.035/3=0.00053851立方米
球有体积吗？、
v=(4/3)πr^3
三分之四乘圆周率乘半径的三次方
带入用计算器算出来就好啦。关键还是要记住公式
