ĀNSWĒR ⏬⏬
=> Let diameter of cirlcle be x
=> we know that Radius = diameter/2
so radius = x/2
According to question
=> Circumference of circle = x+30
= 2πr=x+30
= 2×22/7×x/2=30
= >22x/7 =x+30
=> 22x= 7(x+30)
=> 22x= 7x+210
=>22x-7x-210=0
=> 15x= 210
=> x= 210/15
=> x= 14
=> diameter = x
diameter = 14.
=> radius = 14 /2
=> radius = 7
Therefore radius of the cirlcle is 7
