To solve this problem, we need a formula for calculating the area of a circle.
Knowing the formula for the area of a circle S = n * R ^ 2, where n is the number pi = 3.14, substituting the value 5 as the radius, you can calculate the area of the desired circle.
S = 3.14 * 5 ^ 2
S = 3.14 * 25
S = 78.5 cm squared.
Answer: The area of a circle with a radius of 5 cm is 78.5 cm squared.
