Answer 1

Answer:

radius = d/2

.... radius = 8 ...

Step-by-step explanation:

now. circumference = 2πr .

c= 2×π×8. === 50.29..hope it helps .

Answer 2

Hello !!

Find the radius of this circle.

$\mathsf{r=\dfrac{16}{2}} \\\\\\ \mathsf{r=8}$

Now, you calculate the circunference.

$\mathsf{C=2\pi~r} \\\\\\ \mathsf{C=2\times3.14\times8} \\\\\\ \mathsf{C=6.28\times8} \\\\\\ \boxed{\mathsf{C=50.24~uc~~approx}}$

Final result : 50.24 uc approx.

I hope I have collaborated !
