Question

Find the circonference of circle whose
diameter is 7cm.​

Answer 1

Diameter = 7cm

Radius = 7/2 cm

$Cicumference= 2\pi r = 2 \times \dfrac{22}{7} \times \dfrac{7}{2} = 22cm$

Answer 2

Hey friend,

Here is the answer you are searching for, Circumference of circle = 2πr

Given,

Diameter = 7cm

=>Radius = 7/2cm

Therefore,

Circumference of circle = 2×22/7×7/2

= 2×11 = 22cm

HOPE IT HELPS YOU.
