The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the ordered pair for the center.
(x - (- 3))² + (y - 6)² = 10²
(x + 3)² + (y - 6) = 100
Black 20% 1/5

Brown 35% 7/20
other 20% 1/5
hope it helps!!
Hmmm the easiest way I can imagine to explain this is as follows:
4 times 3 is like 3 added to itself 4 times.
so 4×3= 3+3+3+3= 12. I'm not sure if that's what you meant by drawing a model though.
The answer is b integers
hope this helps
