Find the area of a circle whose diameter is 4!.8 centimeters (cm)!. Remember that the
formula refers to the radius!. Use 3!.14 for p and round your result to the nearest
tenth of a square centimeter!.Www@Enter-QA@Com


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

A= pi radius^2
diameter=2radius
4!.8=2r
r=2!.4
Area= 3!.14(2!.4)^2
A= 18!.1 cm^2Www@Enter-QA@Com
