Hi,

Q 10: that y value would be the same as the length of the radius 3.5

Q 8: 



Shaded area trapzoid

A+=+%28%282%2B+EC%29%2F2%2912+=+90

          EC = 90/6 - 2 = 15-2 = 13

           and BC = 15

A(triangle) = A(larege rectangle) - A(small rectangle) - A(trapezoid)

            = 15*12 - 2*12 - 90 = 66
