Pi x R x 2 = 3.14 x 3 x 2 = 18.84cm
(3cm)2 x pi = 28.274 cm2

The round perimeter of circle is its circumference
The perimeter of a circle is its circumference and it is: 2*pi*radius or pi*diameter
Well, darling, if the diameter of a circle is 3cm, then the radius is half of that, which is 1.5cm. The circumference of a circle is calculated using the formula C = 2πr, so in this case, the circumference would be 2 x π x 1.5cm, which equals 3π cm or approximately 9.42cm. Hope that clears things up for you, sugar.
