Area of the circle is expressed as;
[tex]A\text{ = }\pi r^2[/tex]r is the radius of the circle.
Substitute the radius given into the expression above and calculate the area as shown;
[tex]\begin{gathered} A\text{ =}\pi(5)^2\text{ A = }\pi(5\times5) \\ A\text{ = }\pi(25) \\ A\text{ = 25}\pi \\ A\text{ = 25(3.14)} \\ A\text{ = }78.5m^2 \\ \\ \end{gathered}[/tex]You just multiply 25 with pi which is 3.14
Hence the area of the circle she made in the snow is 78.5m^2
