Answer:

Circumference = 14π feet, Area = 49π square feet

Explanation:

Given that the diameter of the circular flower bed = 14 feet.

First, find the radius of the circle:

[tex]Radius=\frac{Diameter}{2}=\frac{14}{2}=7\;ft[/tex]

(a)Circumference

The circumference of a circle of radius r is calculated using the formula:

[tex]C=2\pi r[/tex]

Substitute r=7:

[tex]\begin{gathered} C=2\times\pi\times7 \\ C=14\pi\;ft. \end{gathered}[/tex]

The circumference is 14π feet.

(b)Area

The area of a circle of radius r is calculated using the formula:

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

Substitute r=7:

[tex]\begin{gathered} A=\pi\times7^2 \\ =\pi\times7\times7 \\ =49\pi\text{ square feet} \end{gathered}[/tex]

The area is 49π square feet.

The first option is correct.
