The three models below are each shaded to represent a different fraction. What is the sum of the fraction represented by the shaded parts of the model? Help

a=r

d=q

c=p

b=s

hope this !

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
