Question

what is the radius of a circle thats 16 units?

Answer 1

Answer:

2.54648ft.

Step-by-step explanation:

r=8/$\pi$(ft.) therefore, the radius of the circle when its circumference is 16 feet is r≈2.54648ft.

Answer 2

Answer:

r =8

Step-by-step explanation:

Therefore,  C = π d .

We know that the circumference,  C , is  16 π , so we can say that:  

16 π = π d

We can divide both sides by  π  to see that  16 = d .

We now know that the diameter of the circle is  16 .

We also know that the diameter has twice the length of the radius.

In equation form:  2 r = d

 2 r = 16

r = 8
