Answer 1

options are
A) 0 to 169π2
B) 0 to 144
C) 0 to 25
D) 0 to 50
E) 5 to 144

Answer 2

what do you think?

Answer 3

hmm idk from where to start (

Answer 4

@k142

Answer 5

yeah longest line is across the diameter.

Answer 6

yes u can find it now

Answer 7

oh ok so line xy will be the combined diameter of circles A and B? @mathmath333

Answer 8

yes of cos

Answer 9

we need to find the diameter of each circle then and then add those 2 diameter, right?

Answer 10

u need to find the diameter of each circle then and then add those 2 diameter

Answer 11

hmm... ok thanks! @mathmath333 i get that )
