What is the area of a circle with a radius of 12? (Use π ≈ 3.14)

To find the area of a circle, you can use the formula:

[ \text{Area} = \pi r^2 ]

In this problem, the radius ( r ) is given as 12. Plugging this value into the formula along with the approximation for ( \pi ):

1. Calculate ( r^2 ):

[ r^2 = 12^2 = 144 ]

2. Now, multiply by ( \pi ) (approximated as 3.14):

[ \text{Area} = 3.14 \times 144 ]

3. Performing the multiplication:

[ 3.14 \times 144 = 452.16 ]

Thus, the area of the circle is 452.16 square units. This calculation confirms that the area using the provided radius and approximation for ( \pi ) leads to the correct answer, which is consistent with the choices given.
