Calculate the area of this circle
2cm radius
The formula to calculate the area of a circle is A = πr², where r represents the radius of the circle. Substituting the given value of radius, which is 2 cm, into this formula, we get:

A = π(2)² = 4π sq cm 

Therefore, the area of the circle is 4π square centimeters, or approximately 12.57 square centimeters.
