Find the missing measure for a right circular cone given the following information. find r if t. a. = 12 and l. a. = 8.

I normally don't give out answers but this one is definitely a 2.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
