Area Of Sectors Help please.
I know you do the angle divided by 360 then multiply by pir^2 like this http://prntscr.com/b976e6
but then why don't we do the same on this one
http://prntscr.com/b9771m
on that, we do the angle divided by 360 just like the first one but we don't multiply by pir^2 instead they multiply 2(pi)(12)
Help would be much-appreciated thanks.

Do you understand the difference between length and area? Read the question again.

(Angle / 360) * circumference of whole circle.

You find the length of an arc by multiplying the radius by theta (angle)

Thank you.
there r two formulas
1. area of a sector: angle/360 x pie x r²
2.arc length:angle/360 x 2 x pie x r
u just have to know the right place to use them!!!!
