Answer:
3 943.84π
Step-by-step explanation:
tienes que usar la fórmula de: pi por radio al cuadrado
Answer:
[tex]314in^{2}[/tex]
Step-by-step explanation:
Circumference is [tex]2\pi r[/tex]
Find your radius
[tex]2\pi r=62.8\\\pi r=31.4\\[/tex]
Let [tex]\pi =3.14[/tex] for simplicity
r=[tex]\frac{31.4}{3.14}[/tex]=10
Now use the equation for the area of a circle to find the area of the clock face.
Area of a circle is [tex]\pi r^{2}[/tex]
Area of clock face is [tex]\pi (10^{2} )[/tex]
=[tex]100\pi[/tex]
=[tex]314in^{2}[/tex]
