A(n)=4+4(n-1)
a(n)=4+4n-4
a(n)=4n
76=4n
n=19
The sum of any arithmetic sequence (series are infinite) is:
(a+a(n))(n/2)
The average of the first and last terms times the number of terms, in this case we found that n=19 so:
19(4+76)/2=760
Answer:
False
Step-by-step explanation:
The volume of a right cylinder is given by the formula:

And the volume if a oblique cylinder is <em>also</em> given by the formula:

Regardless of the height, if the radius are different, then the volume would not be the same.
