The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
Just like any other circle, the area of that one is (pi) times (the square of the radius).
The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
78.53981634 meters.
A = 78.54 cm2
A circle with a radius of 5 units has an area of 78.54 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
