Answer: [tex]\dfrac{7.5}{\pi}\ ft[/tex]
Step-by-step explanation:
We know that , the circumference of a circle is given by :-
[tex]C=2\pi r[/tex] , where r is the radius of the circle.
Formula for radius :
[tex]r=\dfrac{C}{2\pi}[/tex] , where C is the circumference of the circle.
Given : Circumference of circle = 15 ft.
Then , the radius of a circle will be :-
[tex]r=\dfrac{15}{2\pi}=\dfrac{7.5}{\pi}\ ft[/tex]
Hence, the radius of a circle= [tex]\dfrac{7.5}{\pi}\ ft[/tex]
