Question

Find the diameter of the circle whose circumference is 88cm

Answer 1

Circumference =
$2\pi \: r$
Circumference =2*22/7*r
88=44/7*r
88*7/44=r
14=r

Radius =14cm
Diameter =2r
=2*14=28cm

→ Answer :

Diameter  = 28 cm

→ Step-by-step explanation :

Circumference of circle = $2\pi r$

Given Circumference of circle = 88 cm

=> $2\pi r$ = 88

=> r = ( 88 * 7 ) / 44

=> r = 14 cm

But we need to find diameter of circle.

=> diameter , D = 2r

=> D = 2 * 14

=> D = 28 cm
