135度的弧度制是多少

宫侦物4883 - 135度化为弧度是 -
卢傅治13496686430 ______ -135度=-135*兀/180=-3兀/4

宫侦物4883将下列各度化为弧度60° 90° 45° 30° 135° 120° - 30° - 60° - 45° - 90° - 180° - 270° -
卢傅治13496686430 ______[答案] 化弧度是用度数除以180,因为π表示180°所以:60°=π/3 90° =π/245°=π/4 30°=π/6 135°=3π/4 120°=2π/3-30° =-π/6-60°=-π/3 -45°=-π/4 -90°=-π/2 -180°=-π -270°=-3π/2

宫侦物4883数学角度制与弧度制的转化360度内的最好列张表格 -
卢傅治13496686430 ______[答案] 0度=0,30度=π/6,45度=π/4,60度=π/3,90度=π/2,120度=2π/3,135度=3π/4,150度=5π/6,180度=π,210度=7π/6,225度=5π/4,240度=4π/3,270度=3π/2,300度=5π/3,315度=7π/4,330度=11π/6,360度=2π

宫侦物4883半径为10的袁中,135°圆心角所对的圆弧长为 -
卢傅治13496686430 ______[答案] 弧长=半径乘以圆心角(弧度制)=10乘3π/4=15π/2

宫侦物4883半径是5,圆心角135度的弧长是多少? -
卢傅治13496686430 ______ 圆弧长=圆周长*(圆心角/360度)=2*π*5*(135/360)=15π/4= 11.775

宫侦物4883把135°化成弧度数为 -
卢傅治13496686430 ______ 135°÷180°*π =3π/4

宫侦物4883135°=? 弧度. -
卢傅治13496686430 ______ 因为 2兀=360° 兀=180° 所以 135°=(135/180)*兀=3/4兀(Rad)

宫侦物4883 - 135度化为弧度是 -
卢傅治13496686430 ______[答案] -135度=-135*兀/180=-3兀/4

宫侦物4883135°d的弧度数是多少
卢傅治13496686430 ______ 135°π/180°=3π/4 即:4分之3派.

宫侦物488345°=___弧度,135°=___弧度,360°=___弧度. -
卢傅治13496686430 ______[答案] ∵π=180°, ∴45°= π 4弧度. 135°= 3π 4弧度, 360°=2π弧度. 故答案为: π 4; 3π 4;2π.
