Answer:

The area of the clock face is [tex]79\ m^{2}[/tex]

Step-by-step explanation:

we know that

The area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=5\ m[/tex]

[tex]\pi=3.14[/tex]

substitute

[tex]A=(3.14)(5^{2})=78.5\ m^{2}[/tex]

Round to the nearest square meter

[tex]78.5\ m^{2}=79\ m^{2}[/tex]
