So the formula is 2pi(r)(h)+2(pi)(r^2)
2(3.14)(40)(17)+2(pi)(40^2)
so then multiply and add it up and you get
about 14,325 1/3 or 14,325.34
So the pencils all together would be $6 so divide that by 3 and you get D as your answer each pencil costs $2
I think the equation should be
where 3 is the common ratio of the exponential function
so the answer is C.
Only Statement 2 is surely correct.
because there maybe chances that the line L1 and L3 lies above the line L2 and they can also fulfill the condition of perpendicularity so we can't be sure about statement 3 & statement 1 is clearly incorrect
