3n = 1/81; divide both sides by 3 to isolate n:
3n/3 = 1/81 divided by 3. Remember that when you divide, you use the reciprocal and multiply instead!!
n = 1/81(1/3) = 1/243. Now plug 1/243 back in for n, and 3/243 is equivalent to 1/81
SA=4pir^2
SA=4pi13^2
SA=4pi169
SA=676pi ft^2
3x-16y-z+9
i know this is right!
hope this helps!
