It tells you that Area of sector AOB = 8 and r (side of sector) = 5
You need to find the angle O.
I did : o.5 X r^2 X sin O = 8
rearrange to get sin O= 0.64 (8 divided by o.5 X5^2)
so the angle is 0.64, right?
Answer says it is 0.694
Someone please figure this out, I don't understand how they got 0.694?!
Ohh, I just worked it out, you so sin^-1 (o.64) in radians mode.
Never mind, thanks anyway
yh sin to the minus one is the correct method alwayws remeber to to do the inverse operation when finding angles ** <3 x cn u email em anyway though so i can get to know u x if u dont mind x
yh shaima that is the correct method i went through the same qwuestion on a paper and i had a similiar one to this ** <3 ** shaimaa cn u mail me bk on [email protected] ** cheers i very much appreciate it x
An area of a sector is n divided by 360 degrees times by pie times r squared thats the formula i used to do this **
