the ratio of circumference of a circle to its diameter is 22:7. what is the circumference of a curcle of the diameter 15.6m?

C/15.6 = 22/7
=C = 15.6(22/7) = appr 49.03 
Follow the rules carefully......
c=15.6(22/7)=3.1428571
c=15.6*3.1428571=49.028571
Approximately becomes=49.03 
C/15.6 of 22.7,c=15.6(22/7)=49.028 approximately=49.03
