Answer:

b. 12π

Step-by-step explanation:

C= 2πr

R= D/2= 12/2= 6

C= 2x3.14x6

2x6= 12

C= 12π

Solution

Given :-

  • diameter of circle = 12

Then,

  • Radius will be circle= 12/2 = 6

Explanation

Using Formula

Circumference of circle = 2πr

Keep Value

==> Circumference of circle = 2π × 6

==> Circumference of circle = 12π

Hence

  • your answer will be option number b.
