Question

He formula for the circumference of a circle is C = 2r, where r is the radius and C is the circumference. The equation solved for r is r = .
Find the radius of a circle that has a circumference of 16.

r = 4
r = 8
r = 12
r = 16

Answer 1

I think the answer is r=8..
hope this helps!:)

Answer 2

Answer:

Option 2nd is correct

r = 8 units

Step-by-step explanation:

As per the statement:

The formula for the circumference of a circle is C = 2r

where, r is the radius of the circle

To find the radius of the circle.

Circumference(C)  = 16 units

then;

$16 = 2r$

Divide both sides by 2 we have;

8 = r

or

r = 8 units

Therefore, the radius of the circle is, 8 units
