I double checked it and I am always getting (128pi)/9 or 44.68
Area of sector = pi*r^2 * theta/360°
Sub in values: pi*8^2 * 80/360 = 128pi/9
I'm pretty sure you're correct
maybe the book has a typo Isn't it that Area of sector = (1/2) (r^2) (theta) theta is in radians
thanks :)
\[Area = \frac{1}{2} \times 64 \times 80 \times \frac{\pi}{180} \implies 44.65\]
Just trying..
@waterineyes I think it should be 44.68 ? :)
Actually it can be: \[Area = 44.698\]
As value of \(\pi\) is not exact so you cannot say about the exact value..
Here we all are approximating this value..
ohh ok I get it :)
Surely your book is carrying something wrong for this question.. You are right @moongazer
Thanks :)
