Question

OPQ is the sector of a circle who's canter is O , radius x cm and angle POQ is 80°. Given that the area of a sector OPQ is 308 cm^ , calculate the value of x (22/7)

Answer 1

Answer:

area of sector = 308

80/360×πrsquare =308

cancel at least possible calculation

then rsquare /63=7

rsquare =441

radius =+or -21

but radius is always positive
