解答
小圆绕大圆运动一周的距离等于大圆的周长=6π=18.84 cm
小圆绕大圆运动一周转过的圈数=6π/2π=3 圈
推荐
- For an electron in a circle with diameter of 2 Å,Find the wave-functions and energy levels.
- 刹车碟的描述里diameter ,centering diameter ,pitch circle diameter,vented ,solid ,stud supplied
- Find the center and the radius of the circle then graph X^2+y^2-2x-10y+20=0 center() Radius()
- 英语翻译
- （用java解决）设计一个圆类,Circle,有表示半径的protected类型的成员变量radius,获取和设置radius值的
- 铁岭的由来
- 否定疑问句一定表示已知答案的刻意反问吗,
- 4个连续奇数的连乘积是326025，它们的和是_．
