    We have a Slant height of 10, that slant height would be the hypotenuse of a right triangle. Do you know how to do a^2+b^2=c^2 for right triangles?

    So, if you square 6, square X and add them together you'll get 10 squared.

    So, 36 + x^2 = 100

    subtract 36 from both sides, then take the sq rt of both sides

    area of a circle is pi * r^2.......and r = 1/2(d)....and you already know that diameter(d) = x
