Answer 2

Question :-

Find the Circumference of a Circle with Radius 4 cm.

Solution :-

Given,

Radius, r of the Circle = 4 cm;

Value of π = $\bold {\frac{22}{7}\: or\: 3.14}$

-

To Find :

The Circumference of the Circle

We can find the Circumference of the Circle, C by the Formula = $\boxed {\bold {2\pi r}}$ ,

∴ Circumference of the Circle, C = $2 \times 3.14 \times 4$

$\begin {aligned} & \implies 2 \times 3.14 \times 4 \\\\& \Rightarrow 3.14 \times 8 = \bold {25.12\: cm} \end {aligned}$

-

$\mathfrak {\red {Hence, The\: \bold {Circumference\: of\: the\: Circle\: (C)}\: is = \underline {\bold {25.12\: cm}}}}$
