Answer:
A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc
Area = 40 square inches
Square root of 40 gives the side length
Therefore
The side length = 6.32455532 = 6.3 inches
I think it might be 11x-8
I'm really sorry if that's wrong
2 times three is six and 487 divided by 8 is 60.875
A is 4/9 B is 4/15 C is 8/5 D is 3/10
