A circle with a radius of 5 units has an area of 78.54 square units.
First of all, there is no reason to suppose that the area is circular as opposed to rectangular or triangular or some other simple or complicated shape. If, on the basis that the question asks for the radius, you assume that it is a rectangle, then the radius is 0.564 km = 564 metres.
It is 78.5 square units.
It is: 25*pi square m
Area of a circle = (pi) x (radius)2 Radius = 1/2 the diameter = 5 inches Area = (pi) x (5)2 = 25 pi = 78.54 square inches (rounded)
Area of a circle = (pi) x (square of radius) = (pi) x (5)2 = 25 pi = 78.54 square km (rounded)
A circle with a radius of 5 units has an area of 78.54 square units.
For a radius of 5 centimeters the area are 78.53981633974483 square centimeters.

The area of a circle (to the nearest hundredth) with a 5-unit radius is: 78.54 square units.
It is 78.5 square units.
Area = 78.5 square yards.
To calculate the area of a circle with a radius of 5 miles, you would use the formula A = πr^2, where A is the area and r is the radius. In this case, the area would be A = π(5)^2 = 25π square miles. Since π is approximately 3.14, the area would be approximately 78.5 square miles within a 5-mile radius.
78.54 square units (rounded)
It is 72.3 square units, approx.
the square root of 7
Just like any other circle, the area of that one is (pi) times (the square of the radius).
