Question

Find the circumference of a circle whose radius is 14 cm.

Answer 1

Radius = 14 cm
Circumference = 2πr
=> 2 × 22÷7 × 14
=> 2 × 22 × 2
=> 44 × 2
=> 88 cm.

Answer 2

Answer:

$Circumference\:of \: the \: \\ circle (C) = 88\:cm$

Step-by-step explanation:

$Let \: radius \: of \: \\a\: circle \:(r) = 14\:cm$

$We \: know \: that \:\\</p><p>\boxed {Circumference\:of\:a\: circle\:(C)\\=2\pi r }$

Here,

$C = 2\times \frac{22}{7}\times 14\:cm$

$C = 2\times 22 \times 2\:cm $

$C= 88\:cm$

Therefore,

$Circumference\:of \: the \: \\ circle (C) = 88\:cm$
