George is giving his brother a basketball for his birthday. He wants to tie a ribbon around the basketball to make it look like a gift. If the basketball has a radius of 4.5 inches, how many inches of ribbon will George need to be able to wrap the ribbon entirely around the basketball?

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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.
