Answer:

The diameter of the circle is 8.6 centimeters.

Explanation:

The formula for circumference is C = πd

Since both C and π are known then we can easily solve for the diameter.

Substitute the values given and solve.

C = 27cm

π = 3.15

C = πd

27cm = 3.15d

Divide both sides of the equation by 3.15

27cm/3.15 = 3.15d/3.15

8.6 cm = d

d = 8.6 cm
