Question

genna painted a table top that is shaped like a circle . the circumferance of the tabletop is 6 feet which measurement is closest to the area of the tabletop in square feet?

Answer 1

To solve this problem you must apply the proccedure shown below:

 1. You must apply the formula for calculate the area of a circle, which is:

 A=πr^2

 Where A is the area of the circle and r is the radius of the circle.

 2. You have that the diameter is 6 feet, then the radius is:

 r=D/2
 r=3 feet

 3. When you apply the formula shown above, you obtain:

 A=9π feet^2
 A=28.27 feet^2

 The answer is: 28.27 feet^2

Answer 2

Circumference  = 6 ft

circumference = 2*pi*r = 6
 
solve for r:
r = 6/(2*pi) = 0.9554 ft

area = pi*r^2 = 0.9554*0.9554 * 3.14 = 2.866 sq. ft
