The area of the circle is 10

So
$$10=\pi*r^2\\ r^2=\frac{10}{\pi }$$

And the area of the sector is

$$=60/360 * \pi * r^2\\ =\frac{ \pi * \frac{10}{\pi }}{6}\\ =\frac{ 10}{6}\\ =1.\dot6$$

Maybe you should think about the rest yourself  :)

Hey Melody,

I did 10+10 and then subtracted the 1.6666... and got 18.333333... which simplifies to 18 1/3. This answer is wrong. Did I make a mistake? Thanks

remove the segment twice

or (10-1.6)2=16.8
