To calculate the area of a circle, we use the formula :
\pi r^(2), where r is radius.

We replace the numebrs : 144
\pi = 452,389342.... = 452 (rounded)

So, the area of this circle is 452 (and whatever units)

Answer:

Area of circle = 452 units²

Explanation:

We can use the following formula to calculate the area of a circle:

Area = π r²

where r = radius of circle (12 units)

Substituting into the formula:
Area = π × (12)²

= π × 144

= 452.39

= 452 units² (rounded to the nearest whole number)
