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.
The radius of a circle is 45 units. What is the area of the circle? Use 3.14 for π.
