Answer» hii Hii.. My pleasure....? Perimeter of minor sector = 2r + (2πr× thita)/360 Thank u soooo much.... Area of major segment = πr^2 - ( area of minor segment) Area of minor segment =( πr^2 × thita)/360 - 1/2× r^2 × sin thita its ok .... i can understand it??? Sorry...sorry...it\'s not arc...it\'s area of minor and major sector Sorry, area of minor arc = (πr^2 × thita)/360 and area of major arc = πr^2 ( 1- thita/360) Area of major arc = (πr^2 × thita )/ 360 Length of major arc = 2πr - (2πr × thita)/360° Length of minor arc =( 2πr× thita)/360° Thank u too much .. Area of ring = π(R^2 - r^2 ) Area of circle = πr^2 , Circumference of circle = 2πr , Area of semi- circle = πr^2/2 , Circumference of semi- circle = πr + 2r. Yes wait for while Area related to circles....all the formulas i want.. plz anyone.... |
