hey there !
circumference of circle = 2πr
now we have given that circumference = 84
therefore ,
2πr = 84
2×22/7×r = 84
r = 84×44/7 = 13.3636.... cm
hence radius of circle = 13.36cm
hope it helps ,
be brainly ♥ together we go far ,

hey mate
as we know that the formula to calculate the circumference of a triangle is
C = 2πr
by putting the value
84cm = 2 x 22/7 x r
r = 84 x 7 / 2 x 22
r = 13.36
so the radius of the circle is 13.36 cm
