Question

in a circle with radius r an arc subtends an angle of meausure theta at the center . the area of major sector will be?​

Answer 1

Answer:

area of of circle -area of minor sector

Step-by-step explanation:

pie r square -theta of minor sector .pie r Square

Answer 2

Radius of circle = r

Angle subtended to form the arc = ∆ [∆ denotes theta here]

Area of minor sector = ∆/360×πr²

Area of circle = πr²

Area of major sector = πr²-∆πr²/360

= (360πr²-∆πr²)/360

= πr²(360-∆)/360
