The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
78.53.14 * 5 * 5
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.
A circle with an area of 100 square miles has a radius of 5.6418 miles. Or, 5 miles, 1,129 yards, 1 foot, 8.5 inches - more or less.
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.
To calculate the area of a circle with a radius of 5 miles, you would use the formula A = ฯr^2, where A is the area and r is the radius. In this case, the area would be A = ฯ(5)^2 = 25ฯ square miles. Since ฯ is approximately 3.14, the area would be approximately 78.5 square miles within a 5-mile radius.
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
The radius is 1.261 miles.
