Are you looking for the number of cans you and your friend each collected? If yes, here is the solution:
Let x be the number of cans.
4x + 5x = 180
        9x = 180
     9x/9 = 180/9 (divide both sides of the equation by 9)
          x = 20
Now, substitute the values:
4(20) + 5(20) = 180
       80 + 100 = 180
               180 = 180
Therefore, you collected 80 cans and your friend collected 100 cans.
        
             
        
        
        
the arc length is calculated by the formula                                                                     then
   then    or it can be calculated using the circumference of the circle since we have a semicircle the circumference 2πr must be divided by 2  С=2πr:2=πr =8π=<u>25,12</u>
