Answer :
I found C) 43.6 cm^2
I used the fact that the area is equal to radius*angle
But the angle has to be in radians (NOT degrees!)
I change the angle into radians using the proportion
[tex] \pi :180^{o} = x : 100^{o} [/tex]
and I got x=[tex] \frac{100* \pi }{180} = \frac{5}{9} \pi [/tex] rad
So:
Area=[tex]25* \frac{5}{9}*3.14=43.6 cm^{2} [/tex]
