If the height is h, the leaf scar is l, how can you model the pattern using an equation? i need explanation please

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
