Question

formula of area of sector and length of arc. ​

Answer 1

Answer:

area of sector = $πr{^2}× theta/360°$

length of arc =$2πr × theta / 360°$

Answer 2

Step-by-step explanation:

A central angle which is subtended by a major arc has a measure larger than 180°. The arc length formula is used to find the length of an arc of a circle; l=rθ l = r θ , where θ is in radians. Sector area is found A=12θr2 A = 1 2 θ r 2 , where θ is in radians
