Final answer:
The question is about finding the area of a circle using the given radius which is 2 cm. The formula to calculate the area of a circle is A = πr². The shaded or unshaded part of a circle doesn't change the total area.
Step-by-step explanation:
From the question, it seems you are asking about the area of a circle, which is given by the formula: A = πr², where 'A' represents the area, 'π' is a mathematical constant approximately equal to 3.14, and 'r' is the radius of the circle.
If the radius of your circle is 2 cm, then the area can be calculated as follows: A = π*(2cm)². Here, you need to square the radius first which gives you 4 sq.cm and then multiply it with π, giving you 4π sq.cm or approximately 12.57 sq.cm if you use 3.14 for π.
Remember, the unshaded part doesn't affect the total area of the circle, unless a different shaded area is subtracted from it.
