Answer 1

Answer:

Circumference of circle is $\frac{176}{7}\;cm$

Step-by-step explanation:

Given :-

Diameter of a circle = 8 cm

To find :-

Circumference

Solution :-

$Radius\;=\;\frac{Diameter}{2}$

• $Radius\;=\;\frac{8}{2}$

• $Radius\;=\;4\;cm$

$Circumference\;=\;2\;\pi\;r$

• $2*\frac{22}{7}*4$

• $\frac{44}{7}*4$

• $\frac{176}{7}$

∴ Circumference of circle is $\frac{176}{7}\;cm$
