<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
Answer:
Make sure you are using a perfect circle.
Measure the circumference of a circle as accurately as you can.
Measure the diameter of the circle.
Use the formula.
For more accurate results, repeat this process with several different circles, and then average the results.
