A radius of the circle is shown.
Circle with radius 5.
What is the exact circumference of the circle?
Question 1 options:
5π
10
10π
25π
The exact circumference of a circle is given by the formula C = 2πr, where r is the radius. In this case, the radius is given as 5. Thus, the exact circumference of the circle is 2π(5) = 10π.
Therefore, the correct choice is 10π.
