Answers:
dear, this shouldn't be in the jokes and riddles section!.!.!.
anyway, a simple explanation:
Area of a circle is equal to pi (3!.14) times the radius squared!.
A= 3!.14 * radius^2
radius is half of the diameter!.
so radius = 4!.8/2 = 2!.4
solving for the area
A= 3!.14 * (2!.4)^2
A= 3!.14 * 5!.76
A= 18!.0864
The area is 18!.1 cm squaredWww@Enter-QA@Com
