Answer 2

The circumference of a circle whose diameter is 14 cm is 44 cm

Given :

The diameter of a circle is 14 cm

To find :

The circumference of the circle

Formula :

The circumference of a circle of radius r unit

= 2πr unit

Solution :

Step 1 of 2 :

Find radius of the circle

Here it is given that the diameter of the circle is 14 cm

So radius of the circle

$\displaystyle \sf{ = \frac{14}{2} \: \: cm }$

$\displaystyle \sf{ = 7 \: \: cm }$

Step 2 of 2 :

Find circumference of the circle

Hence circumference of the circle

$\displaystyle \sf{ = 2\pi r \: \: cm}$

$\displaystyle \sf{ = 2 \times \frac{22}{7} \times 7 \: \: cm}$

$\displaystyle \sf{ = 44 \: \: cm}$

∴ The circumference of a circle whose diameter is 14 cm is 44 cm
