Answer 1

Question:

Find the circumference of a circle of diameter 56 cm.

Given:

Diameter : 56 cm

To find:

Circumference of circle

$\huge \mathtt {(2πr)}$

Where, r = radius of circle

Answer:

176 cm

Solution:

Diameter = 56 cm

Radius = $\large \frac {1}{2}{× Diameter}$

= $\large \frac {1}{2}{× 56}$

= 28

Circumference of circle = $\huge \mathtt {2πr}$

= $\large{2 ×} \frac {22}{7}{× 28}$

= 176 cm
