Question

find the area of a sector of a circle whose radious is r and length of the area is l​

Answer 1

Answer:

ans

theta /360× pie r ^2

this is your ans

Answer 2

given :- A circle with centre O having radius r and length of area l.

hence; find area of sector.

solution:-

we know that;

area of sector = (angle AOB/360degrees)× (pie × r^2)

hence area of sector = (theta /360 degrees)×(pie × r^2)
