Answer: 8cm
Step-by-step explanation:
If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
Answer:
Step-by-step explanation:
The diameter of the circle is 6mm
Circumference formula
C=pi d
18.84mm=3.14(d)
Divide by 3.14 to isolate for x
18.84mm/3.14=d
D=6m
