Question

Find the circumference of a circle that has a radius of $fraction numerator 1 over denominator 2 end fraction$ .

$- π$
12 $π$
$π$
2 $π$

hint Hint:

Circumference = 2 × radius × $pi$

The correct answer is: $pi$

Recall the formula for finding the circumference of a circle:
Circumference = 2 × radius × $pi$
We can substitute in the value for the radius in order to find the circumference of the circle in question. Circumference = $2 cross times fraction numerator 1 over denominator 2 end fraction cross times pi$
Solve.
Circumference = $fraction numerator 2 over denominator 2 end fraction cross times pi$
Simplify.
Circumference = $pi$
