2) d = 10 so,
C =?
A = ?

C = 10pi
A = 25pi
Diameter is twice the radius. So r = 5. Then plug into the equations C = 2pi*r and A = pi*r^2, respectively.

d=10
r=d/2=5
C=2 pi r
=2 pi 5
=10 pi
A=pi r^2
=pi 5^2
=25 pi

Never noticed that. I haven't been on Y!A much lately, so I don't know what's going on, but as far as I know Lexi is a Leo and Same Ol' is an Aries. I might be wrong though. They might be frenemies :P Oh right, I was totally wrong then, haha. Sorry about that.

are we doing your homework??
circ = 2*pi*radius
area = pi*radius^2
