The formula for the circumference of a circle is 2(pi)(r). From your example, r=4 cm
So the answer would be 2(pi)(4 cm), or 8pi cm (this is a little more than 24 cm, since pi=3.14).

What is the radius of a circle if its a diameter 4 cm?
Its radius is: 4/2 = 2 cm
What is the probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm?
The probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius). Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
