Question

Can someone please help i suck at math!!!!!!:(

Answer 1

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
