How do you calculate the area of a sector in radians??? Is this correct?
I have the formula below but i'm not sure if its correct. The conversion is for changing the angle (theta) into radians.
conversion= (180/pi) * theta
area of sector = (conversion/ (2*pi) )* pi * radius * radius
Is this formula correct???
Thanks!!!!!!!!!!
thanks sertrbl!!!!
I was a bit worried when the first answer told be about sin lol
Thanks again!!!!
r²(θ-sinθ)/2, where θ is the angle in radians
