Work out the perimeter of this semicircle with radius 3cm. Give your answer in terms of π

kondaur [170]

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

A semicircle is given with radius of 3cm .

And we need to find the perimeter of the semicircle . We know the perimeter as ,

$:\implies$ Perimeter = πr

$:\implies$ Perimeter = 3cm × π

$:\implies$ Perimeter = 3π cm .

Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,

$:\implies$ Perimeter = 3π + 6 cm

We were supposed to give answers in terms of π .

<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
