Show all you're your working clearly.
Give your answer to 2 decimal places.

Answer 1

Explanation:

diameter = 6 cm

Perimeter of circle =πd

= 3.14 * 6 = 18.84 cm

If it is to find the perimeter of semicircle, then

Perimeter of semicircle = Perimeter of circle/2 + diameter

`=(18.84)/(2)+6\\\\= 9.42+6\\\\`

= 15.42 cm
