Question

all formulas of area related to circle class 10

Answer 1

here are the formulas of area related to circle =>

=>area of circle =πr^2

=>circumference of circle =2πr

=>area of semicircle =πr^2/2

=>area of minor arc =theta /360.πr^2

=>area of major arc =area of circle - area of minor arc

=>area of segment =area of sector -area of triangle

=>area of segment = π .theta /360 -sinπ/2

=>length of arc =theta /360 . 2πr

=>area of sector =r/2 . length of arc

=>area between concentric circles =π(R^2 - r^2)
