Answer 1

Answer:

$\fbox\purple{Question}$

• Find the circumference of a circle when diameter of a circle is 14cm.

$\fbox\purple{Given}$

Diameter = 14 cm

Radius = $\frac{Diameter}{2} = \frac{14}{2}$ = 7cm.

$\fbox\purple{To\:find:-}$

We have to find the circumference of the circle.

So, let the circumference of the circle = x

$\fbox\purple{Formula}$

Circumference = 2πr = 2 × $\frac{22}{7}$ × Diameter

$\fbox\purple{Solution}$

Diameter = 14 cm

Radius = $\frac{Diameter}{2} = \frac{14}{2}$ = 7cm.

Circumference = 2πr = 2 × $\frac{22}{7}$ × Diameter

= 2 × $\frac{22}{7}$ × 14 = $\fbox\red{44\: cm}$
