Find the circumference of the circle. Round your answer to the nearest hundredth

in the center of the circle is 4.5 ft.

a 14.14

b 15.90

c 16.82

d 17.43

Verified Answer :

2 π radius

or 

π*diameter

Answer:

a. 14.14 ft²

Step-by-step explanation:

The measurement given refers to the diameter of the circle. The formula for the circumference and area uses the radius of a circle, therefore it is always safer to use radius instead of diameter

The radius is half of the diameter, which is 2.25 ft.

\(A=2*r*\pi \\A=2*2.25*\pi \\A=14.14ft^{2}\)
