where d= diameter of the circle.
just plug in!

Answer 2

what?

Answer 3

if you don't understand,
then first find the radius
radius = diameter/2 =... ?

Answer 4

What you have to remember is that Area=pi r^2.
So area is r which is 6/2 and then square that so you get 9 and then add the pi at the end. So it is B.
