Question

UNIT 8

Answer 1

For the first figure the Circumference of the circle is: 5.3$\ip$$\pi$ cm.

For the second figure the Circumference of the circle is: 80$\ip$$\pi$ inch.

What is Circumference of the Circle?

The circumference of a circle is defined as the linear distance around it.

i.e.,  $C= 2 *\pi*r$

• For First Figure,

Circumference of the circle:

$= 2 *\pi*r$

$= 2 *\pi* \frac{5.3}{2}$

$= 2 *\pi*2.65$

$Circumference= 5.3*\pi cm$

• For the second Figure,

Circumference $= 2 *\pi*r$

$= 2 *\pi*40$

 $= 80 *\pi$

$Circumference =80\pi \;inch$

For the first figure the Circumference of the circle is: 5.3$\ip$$\pi$ cm.

For the second figure the Circumference of the circle is: 80$\ip$$\pi$ inch.
