An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.
A=pi times R squared If the radius is 5, the area is 25pi
The area of a circle of radius r is pi*r*r
It is 78.5 square units.

The area of a circle, if the radius is 5 cm, is: 78.54 cm2
The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
An area of 5km radius implies a circle. The area of a circle of radius r is {pi}r2. Area ~= 3.14 x 5 x 5 km2 ~= 78.54 km2.

A=pi times R squared If the radius is 5, the area is 25pi
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.
The area of a circle of radius r is pi*r*r
About 78.54m2
Just like any other circle, the area of that one is (pi) times (the square of the radius).
Area = 78.5 cm2
if you double the radius (or diameter) , you get four times the area. area of a circle = pi * radius squared
