Answer:
The diameter of a circle is twice the radius.
The circumference of a circle is the diameter multiplied by Pi.
So, for a circle of 5 cm radius:
Diameter is (2r) = 2 (5 cm) = 10 cm.
The Circumference = ( Pi ) ( 10 cm) = approx.-=31. 416 cm. = 0.31416 m
Step-by-step explanation:
Ratio of radius to diameter = 1 : 2
