The height of a cylinder is three times the diameter of the base. The surface area of the cylinder is 126 PI squared feet. What is the radius of the base?

30

you have to do the math of 9x2=18 then you add 12 to your answer and your answer is 30

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
