Answer:

Sarah is Correct

Step-by-step explanation:

If we are given the area of a circle as 44 Square Centimeter, we know that:

Area of a Circle[tex]=\pi r^2[/tex]

Circumference of a Circle [tex]=2\pi r[/tex]

Therefore, from the area, we can obtain the value of the radius to calculate the circumference of the circle:

[tex]\pi r^2=44\\r^2=\dfrac{44}{\pi} \\r=\sqrt{\dfrac{44}{\pi} }[/tex]

Therefore:

Circumference of the circle[tex]=2\pi \sqrt{\dfrac{44}{\pi} }[/tex]

=23.51 centimeters.
