(a) The perimeter of the shape is the sum of half a circumference and the diameter itself.
The circumference of a circle with radius
is
, and since
we can write the circumference as

So, half a circumference is

Ad we get the perimeter by addind the diameter:

(b) Given the perimeter, we can solve for
:

So, we can divide both sides by the parenthesis and we have
