Question:
Solution:
The area of a circle of radius r is given by the following formula:
[tex]A=\pi r^2[/tex]
In this case, r = 5m. Thus, the area of the clock face would be:
[tex]A=\pi r^2=3.14(5)^2\text{ = 3.14 x 25 = 78.5}\approx\text{ 79}[/tex]
then, the correct answer is:
[tex]A=\text{ 79 square meters}[/tex]
