Find the diameter and radius of circle given the cirumfrence as 61.6m (take pi 22/7)


ANSWER.


FORMULA USED


Circumference of circle =2πr


so,


2πr=61.6m





$2 \times \frac{22}{7} \times r = 61.6m$




$r = 61.6 \times \frac{7}{22} \times \frac{1}{2}$





$r = \frac{431.2}{44}$



r=9.8m


so,

diameter =2r

mean diameter =2×9.8

=19.6m



HENCE

Diameter of given circle =19.6m


Radius of given circle=9.8m
