<span>divide the area of the smaller circle by the area of the bigger circle.
50.27 / </span>314.16 = about 0.16
make it into a fraction
16/100 = 4/25
you answer is 4/25
a3=9
assuming the pattern is constant, a3 is right in the middle of a1 and a5 so the answer would be right in the middle of 6 and 12. the average of 6 and 12 is 9, so a3=9.
hope this helps!
U use y=mx+b to find the slope, and the answer would be m=-3
