First find the square root of 900 to get one side of the square, which is 30 inches.
Formula for area of a circle: pi times the radius(squared)
The radius is 15 because one side of the square equals the diameter of the circle. 15 squared is 225.
3.14x225=<u>706.5 inches squared
</u>I hope this helps, because I did not have a diagram of the problem, but this should be the answer if the circle is inscribed in the square.<u>
</u>
The equarion to this problem is 30 + 100 + 50x = x
I believe it would be (-4, 8); because when x = -4, y = f(x) = 8.
Multiply 3 times 6 and then you get 18 all of the possible outcomes
