Acircle has an area of 36π square centimeters. what is the diameter? a. 6 cm c. 12 cm b. 1,296π cm d. 12π cm

c. 12 cm

Step-by-step explanation:

The area of any circle is:

  A = π

where r is the radius of the circle

But, r =

where r is the radius and D is the diameter of the circle. Thus,

      A =  π

But, A = 36  π

So that,

  36  π = π

   36  π = π

cross multiply,

144π = π

⇒ 144 =

   D =

Therefore, D = 12 cm
