Answer 1

$\underline{\textbf{Hey Mate Here Is Your Answer}}$

$\underline{\bold{Given\:That..}}$

Radius Of A Circle Is Equal To 4.9 cm , We Need To Find It's

Circumference...

So Now Let's Move For The Solution ...

$\underline{\bold{Solution..}}$

Now According To Question The Radius Of The Circle Is Equal To

$\bold{Radius = 4.9 \: cm}$

And We Need To Find The Circumference...
So Now We Know The Formula Of Finding Circumference Of A Circle ...

That Is ..

$\boxed{\bold{Circumfrence\:=\:2 \pi r}}$

Where " r " = Radius ...

So Now Applying This Formula In Our Question Where

$\textbf{Radius = r = 4.9 cm }$

And

$\bold{We \:Can\: Take\: \pi\: =\: 22/7 \:( Approx )}$

So Now We Have ...

$\bold{circumfrence \: = \: 2 \times \frac{22}{7} \times 4.9}$

Now We Can Cancel 4.9 With Denominator 7 ( As 7 × 0.7 = 4.9 )

So We Have ..

$\bold{circumfrence \: = \: 2 \times 22 \times 0.7}$

That Is ..

$\bold{circumfrence = 44 \times 0.7}$

So We Have...

$\bold{circumfrence = 30.8cm}$

$\textbf{Hence The Required Answer Is }$

$\boxed{\boxed{\bold{Circumference\:=30.8\: Cm}}}$

$\large{\bold{Thanks}}$
