Quadrilateral 78874

Given is a quadrilateral ABCD inscribed in a circle, with the diagonal AC being the circle's diameter. The distance between point B and the diameter is 15 cm, and between point D and the diameter is 18 cm. Calculate the radius of the circle and the perimeter of the quadrilateral ABCD.

Correct answer:

r =  1 cm
o =  0 cm

Step-by-step explanation:

h1=15 cm h2=18 cm  AC=2r  x+y=r z+w=r r2=h12+y2 r2=h22+z2  r=1=1 cm
o=a+b+c+d=0 cm
