Given : Area of a Circle B is 144π ft²

We know that :

$\bigstar \ \ \boxed{\textsf{Area of Circle is given by : $\mathsf{\pi r^2}$}}$

$\implies \mathsf{\pi r^2 = 144\pi}$

$\implies \mathsf{r^2 = 144}$

$\implies \mathsf{r^2 = (12)^2}$

$\implies \mathsf{r = 12}$

It means the Radius of Circle B is 12 ft

Now we need to find the Circumference of the Circle B

We know that :

$\bigstar \ \ \boxed{\textsf{Circumference of a Circle is given by : $\mathsf{2\pi r}$}}$

$\implies \textsf{Circumference of Circle B is : $\mathsf{2\pi * 12}$}$

$\implies \textsf{Circumference of Circle B is : $\mathsf{24\pi \ ft}$}$

Answer : Option B
