The area of a circle can be calculated using the formula: ( A = \pi r^2 ), where ( r ) is the radius of the circle.
Given that the radius is 5, we can plug in the value of 5 into the formula to find the area:
( A = \pi \times 5^2 ) ( A = \pi \times 25 ) ( A = 25\pi )
Therefore, the area of a circle with radius 5 is ( 25\pi ) or approximately 78.54 square units.
