Question

what is the circumference of a circle of radius 3.5cm?

Answer 1

Heya ur answer...

Circumference of circle=2πr
r,radius given =3.5cm

=2×22/7×3.5
=22cm

hope it helps✌

Answer 2

Here is the answer

We know that,

$\bf{Circumference = 2πr}$

Therefore,

$\bf{= 2 \times \frac{22}{7} \times 3.5}$

$\bf{2 \times \frac{22}{ \sout7} \times \sout{3.5} \: 0.5}$

$\bf {= 2 \times 22 \times 0.5}$

$\bf{ = 44 \times 0.5}$

$\bf{= 2.2 \: cm}$

Hence,
The circumference of the circle is 2.2 cm.
