Question

What is the exact circumference of the circle?

Answer 1

How to find the radius/circumference of a circle is to find half of the diameter..

In this case we are given the diameter being 16. So lets find half of this

16/2 = 8

So the radius/circumference of the circle is 8

Its that easy haha

I hope this helps!
Brainliest is always appreciated if you feel its deserved!

Answer 2

To find the circumference of a circle you would use the equation 
2$\pi$r
2 times Pi times the radius
In this equation the radius is 8
Pi is equal to 3.14159265.... But is rounded to 3.14 when multiplying
8 times 3.14 is 25.12
25.12 times 2 is 50.24
Even when I used the larger numbers for Pi i still got in the 50's so there is most likely a typo
