282.6 square units
141.3 square units
6358.5 square units
5463.8 square units
The formula for the area of a circle is A = πr², where r is the radius of the circle.
Given that the radius is 45 units, we can plug this into the formula:
A = 3.14 * (45)²
A = 3.14 * 2025
A = 6358.5 square units
Therefore, the area of the circle is 6358.5 square units.
So the correct answer is: 6358.5 square units.
