Answer 2

Answer:

17.9845 cm

Step-by-step explanation:

The circumference of a circle or the perimeter of a circle refers to the measurement of the border across any 2D circular shape including the circle.  However, the area of the circle describes the area engaged by it. Let us more about the circumference of the circle here in detail.

Using the formula,

C = 2 π r

Solving for,

r = C/ 2 π = 56.5/ 2 π = 8.99225 cm

Radius = 8.99225 cm

So, diameter = 2 x radius

= 8.99225 centimetres x 2 = 17.9845 centimeters.
