The circle above has a radius of 4 cm. What is the area of the circle?
The area of a circle is calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius of the circle.
Given that the radius of the circle above is 4 cm, we can substitute this value into the formula:
A = π(4 cm)^2
A = π(16 cm^2)
A = 3.14159 * 16
A = 50.2656
Therefore, the area of the circle is approximately 50.27 square centimeters.
