If a circle has a radius of 5cm, what is the area?
To find the area of a circle, you can use the formula A = π * r^2, where A is the area and r is the radius of the circle.
Given that the radius of the circle is 5cm, you can substitute r = 5 into the formula:
A = π * (5)^2
A = π * 25
A = 25π
Therefore, the area of the circle with a radius of 5cm is 25π square cm. You can also approximate this value by using 3.14 or any other appropriate value of π to get a numerical answer.
