Question

find the radius and
diameter of a circle whose circumference is 92.4 CM

Answer 1

Heya !! ☺

Let 'r' be the radius of the circle.

Circumference of circle = 92.4 cm

2πr = 92.4

=> 2 × 3.14 × r = 92.4

=> 6.28 × r = 92.4

=> r = 92.4 / 6.28

=> r = 14.71 cm


Diameter = 2r

=> 2 × 14.71

=> 29.42 cm

Answer 2

circumference = 2* pie *r
92.4= 2* 22/7*r
92.4*7/22*2=r
r=14.7
.
d =r*2
14.7*2
29.4
