I will take the sugestion, so 85 units per month (100 is full capacity)
so while doing maintinance, the 6 months is wasted, 0 ouput, basically 85*6=510 lost
now we have to see how many months x it takes for the output to match
the output that would have been is 510+85x the output now is 120x so 510+85x=120x minus 85x both sides 510=35x divide both sides by 35 14.57=x round up 15 months needed
Given the circle has a radius of 64, to get the value of the radius,r we shall proceed as follows. Area=πr^2 Thus; 64=πr^2 64/π=r^2 r^2=20.3718 r=sqrt(20.3718) r=4.5135 Therefore the length of radius,r=4.5135 units
