The equation for the area of a circle is:
A = \pi r^{2}
The diameter of the circle is 44cm, to get the radius you divide the diameter by 2, or the radius is half of the diameter
\frac{d}{2} = r
\frac{44}{2} = r
22 = r
Now that you have r, you can plug it into the equation
A = \pi (22)^{2}
A = \pi (484)
A = 1520.5 cm²
The answer would be closest to the first multiple choice answer
