The area of a circle is \pi r^2, where r is the radius of the circle. The diameter of a circle is the length of a line that passes through the center of the circle and stops at the perimeter of circle. The radius of a circle is half the diameter. Divide the diameter by 2 to find the radius.
1. 2.8 m / 2 = 1.4 m
2 . [tex] \pi (1.2m)^2 [/tex]: Plug in the value we just found for r.
3. [tex]\pi 1.44m^2[/tex] : Use the order of operations (PEMDAS).
4. [tex]\pi * 1.44m^2 = ~4.52 m^2[/tex]
The area of the circle is equal to [tex]4.52 m^2.[/tex]
