The circumference of one wheel is 20mm longer than of another wheel. The product of the two circumference is 144300mm. Calculate the dimension of the two wheels.
Dear Studentgiven thatc1=c2+20andc1*c2=144300 mm^2therefore(c2+20)*c2=144300hence c2^2+20*c2-144300=0this is a quadratic equation in c2 and can be solved using the standardprocedureas c2=(-20+760)/2= 370The negative value will be ommitted.c1= c2+20c1=390.circumference= 2*pi*rfinding radius from the obtained circumference.r1= 58.88 mmr2= 62.07 mmThanks
