hold on lol trying to attatch it

Answer 2

:)

Answer 3

its not perfect :/// lol sowwy

Answer 4

see its a right angled triangle /.......
apply pythogorean theorem

Answer 5

A. 3 inches
B. 2 inches
C. 5 inches
D. no solution

Answer 6

but i dont know the radius

Answer 7

hint: expand right side ..... r^2 terms will cancel out

Answer 8

uh

Answer 9

i still dont get it

Answer 10

can you distribute (r+2)^2 ..... FOIL (r+2)(r+2)

Answer 11

is it a?

Answer 12

why do you think its a) ?

Answer 13

because it just makes sense. lol. 2+3= 5. and AB is 4. and AC is the hypotenuse so its longer. it wouldnt be b

Answer 14

@dumbcow

Answer 15

thats correct :), but what if you didn't have multiple choice

do you understand the pythagorean thm and how to solve for radius
