Answer:

r = 4.2 cm

d = 8.4 cm

Step-by-step explanation:

The radius is given. It is line from the middle of the circle to the outer edge of the circle

r = 4.2 cm

The diameter is from the outer edge of the circle, passing through the center, to the opposite outer edge ( and it is a straight line)

It is 2 times the radius

d = 2r = 2 * 4.2 = 8.4 cm
