<span>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: </span>(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
