The radius of Matilda's bracelet is 2.784 inches

Step-by-step explanation:

Given,

The circumference of Matties bracelet is = 7 inches

The bracelet of Matilda is 2.5 times of Matties's bracelet

So, the circumference of Matilda's bracelet = 2.5 × 7 inches = 17.5 inches

To find the radius of Matilda's bracelet

Formula

The circumference of circle of radius(r) = 2πr inches

According to the problem,

2πr = 17.5

or, r = [tex]\frac{17.5X7}{22X2}[/tex]

= 2.784 inches (approx)
