Andrew= 4 yr.old
Sara=12 yr. old
Tom= 12 yr. old
Basically, what I did was guess and check, but there are other ways also. When I came with Andrew's age of 5 and it was pretty close, I went down to 4 years old and that worked perfect because that way both Tom and Sara are 12 years old.
Answer:
a) The center coordinates O is (0,0)
b) The radius C = 15
Step-by-step explanation:
The given equation of the circle is :
Now, general form of the equation of the circle is:
where (h,k) are the center co -ordinates and r is the radius of the circle.
Comparing the general equation with the given equation, we get
So, here the center coordinates (h,k) = (0,0)
And the radius of the given circle is r = 15
