Answer:
π
Step-by-step explanation:
Area of a circle = [tex]r^{2}[/tex]π
1. Find the radius.
You should view the "length" of this circle as the diameter of the circle. So the diameter of the circle is 2 cm ⇒ r = [tex]\frac{2}{2}[/tex] where the numerator is the diameter of the circle (2) and the denominator is always 2. So the radius is 1. The radius is half the length of the diameter.
2. Substitute the values.
A = [tex](1)^{2}[/tex]π Always put the radius in parentheses before evaluating.
A = π [tex]1^{2}[/tex] = 1 and 1 · π = π
