Answer:

11.31

Step-by-step explanation:

<h3>given:</h3>

The diameter of the circle is 3.6 units.

<h3>to find:</h3>

Value of "a"

<h3>steps</h3>

Circumference of a circle in terms of radius:
Circumference = 2 · π · r = 2 · 3.14 · 1.8 = 11.31 (*)

In terms of diameter:

Circumference = π · d = 3.14 · 3.6 = 11.3 (*)

In terms of area:

Circumference C = √4·π·A = √4·π·10.18 = 11.31 (*)
