Find the circumference of the circle .the diameter is 6cm
Vinvika [58]

Answer:

18.84cm

Step-by-step explanation:

There is a formula which for the diameter is pie (3.14) times the diameter. Now if you have the radius it would be pie (3.14) times 2 times whatever the radius would be. Now you could use either formula for this, just divide the diameter by two to get 3.

So 3x2x3.14=18.84cm

So then you could just multiply 6x3.14 and still get 18.84cm
