Answer:
226.19
Step-by-step explanation:
area of a cylinder is 2 times pi times radius time height plus 2 times pi times radius squared
radius=6/2=3
height=9
substitute in your values and get 226.19cm squared
36 throws because you divide 60 by five and get 12 and then multiply 3 by 12 giving you 36, are you sure this is high school
Hello! To find any number in the arithmetic sequence we can use a formula!
It is given by

The geometric sequence formula goes by

So for this we notice that there's a start of 5 and is being added 3 to get 8.
and then each time it is added by 2 more to get the next time
5
5+ 3 = 8
8 + 5 = 13
13 + 7 = 20
20 + 9 = 29
29 + 11 = 41
41 + 13 = 54
54 + 15 = 69
69 + 17 = 83
Your formula is

Where n starts at 2 not 1
Peter's account is 910-40x, and Marla's account is 470-2x. This is a system, so you must find the number that makes both equations end up with the same number. Basically trial and error. Here is what I did:
Let's try the number 10. 910-400=510 and 470-20=450. I need a higher number.
Let's try 13 next. 910-520=390 and 470-26=444. Now the number has to be lower.
Let's try 12. 910-480=430 and 470-24=446. Close, and a little lower.
11.5 is too low, and 11.7 is too high. 11.6 has Equation 1 at 446 and Equation 2 at 446.8. Very close!
It is somewhere around 11.6. I hope that this can give you a start in figuring it out, because I don't believe in giving the complete answer, because then you do not learn anything from it.
