Answer:
12
Step-by-step explanation:
The circumference of a circle is given as
Circumference = 2πr
Where; r is the radius of the circle
The diameter of a circle is 2 times the radius of that circle. It cuts the circle into 2 equal halves
Given, circumference of the circle = 12π
12π = 2πr
make r the subject by dividing both sides by 2π
12π/2π = 2πr/2π
r = 6
Diameter = 2r
= 2 X 6 = 12
