A, B,C or D.???

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1

Find the dimensions of the circle. area = 64π in.² r= in.

What is the value of x? assume that the line is tangent to the circle.
