Answer 2

Answer:

Circumference of the given circle (C) = 44 cm

Step-by-step explanation:

Given radius of a circle(r)=7 cm

We know that,

\boxed {Circumference\: of \: a \: circle (C)\\=2\pi r }

Now,

C = 2\times \frac{22}{7} \times 7\:cm \\=2 \times 22 \:cm\\=44\:cm

Therefore,

Circumference of the given circle (C) = 44 cm
