all formula of circle send me the photo​

Answer 1

Answer:

Circle Formulas in Math :

•Area of a circle (A ) = π r 2 =( π/4 ) D2 = 0.7854 D2 ...

•Diameter of a circle (D) = √(A/0.7854).

•Here angle between two radii is ” θ” in degrees. . ...

•The area of the sector = (θ/2) r 2

•Sector angle of a circle θ = (180 x l )/ (π r ).

•Perimeter of the segment = (θ π r / 180) + 2r sin (θ/2).
