Suppose current radius  of circle is D
radious =D/2
old circumstance=2*pi*D/2=pi*D
suppose increase 10% of Diameter is 1.10D
radious=1.10D/2
new circumstance =2*pi*1.10*D/2=pi*1.10*D
increase % of circumstance=(new circumstance-old circumstance)/old circumstance *100
=(pi*1.10*D -pi*D)/pi*D *100
=10%
circumstance increased by 10%
