Equation of circle

Find an equation of the circle with indicated properties:
a. center at (-3,5), diameter 20.
b. center at origin and diameter 16.

Final Answer:

a : (x+3)^2+(y-5)=10^2
b : x^2+y^2=8^2

Step-by-step explanation:

d1=20 r1=d1/2=20/2=10 A=(3,5)  (xAx)2+(yAy)2=r12  a:(x+3)2+(y5)=102
d2=16 r2=d2/2=16/2=8 B=(0,0)  (xBx)2+(yBy)2= r22  b:x2+y2=82
