Alright, lets get started.
The distance around the edge of the table top is 4.7 feet.
It means, circumference will be 4.7 feet.
[tex]2\pi r = 4.7[/tex]
Dividing 2pi in both sides
[tex]r = \frac{4.7}{2\pi } = 0.748[/tex] feet
It means the radius of the circle table = 0.748 feet
So the area will be = [tex]\pi r^2 = \pi *0.748^2 = 1.76[/tex] square feet
So the area Nami needs is 1.76 square feet. : Answer
Hope it will help :)
