Answer:

18.84

Step-by-step explanation:

because the radius is 3, the diameter is 6. And the circumference is C=pi(d).

In this case, C=3.14(6), and 3.14*6=18.84

Answer:

C= 18.85 if you want circumference, A= 28.27 if you want area.

Step-by-step explanation:

For circumference, you would want to multiply the radius with pi (pi x 3.14). The formula for it that you could keep in mind is, "C = 2 pi r" For area, the formula of the circle is, "A = pi r^2" or "Area equals pi r squared"
