A belt is drawn tightly around three circles of radius $10$ cm each, as shown. the length of the belt, in cm, can be written in the form $a + b/pi$. what is the value of $a + b$?

A belt is drawn tightly around three circles of radius 10 cm. Then, the perimeter of the 3 circles would be:

3 * circle perimeter

3 * 2 * pi * r

6 * pi * 10 = 60 * pi

Since the symbole messed up, I will give 2 possible answer

If the equation expressed as (a+b) / pi, then the value of a+b would be:

(a+b) / pi = 60 * pi

a+b = 60*pi * pi

a+b = 60*pi^2

If the equation expressed as (a+b) * pi, then the value of a+b would be:

(a+b) * pi = 60 * pi

a+b = 60
