The circumference of a circle whose diameter is 3.5 cm is 11 cm

Given :

The diameter of a circle is 3.5 cm

To find :

The circumference of the circle

Formula :

For a circle of radius r unit the circumference of the circle = 2πr unit

Solution :

Step 1 of 2 :

Find radius of the circle

Here it is given that the diameter of a circle is 3.5 cm

The radius of the circle

= r

= 3.5/2 cm

= 1.75 cm

Step 2 of 2 :

Find circumference of the circle

The circumference of the circle

= 2πr cm

$\displaystyle \sf{ = 2 \times \frac{22}{7} \times 1.75 \: \: cm }$

$\displaystyle \sf{ = 11 \: \: cm }$

The circumference of a circle whose diameter is 3.5 cm is 11 cm
