Question

Jennifer painted a tabletop that is shaped like a circle. The circumference of the tabletop is 6pi feet. Which measurement is closest to the area of the tabletop in square feet?

Answer 1

Answer:

Answer: 28 square feet.

Step-by-step explanation:

Circumference of a circle with radius r is given by :-

C=2\pi rC=2πr

Given: The circumference of the tabletop = 6π feet.

Therefore, the circumference of circle is given by :-

Area of circle: A=\pi r^2A=πr

2

, where r is radius of circle.

Now, Area of circle: A=\pi (3)^2=9\pi=28.2743338823\approx28\ ft^2A=π(3)

2

=9π=28.2743338823≈28 ft
