<span>the question does not present the picture, but this
does not interfere with the resolution</span>
we know that
When a rectangle with a width of 2.5 feet and a length of 8 feet rotates it makes a cylinder with a radius r = 2.5 ft and a height h = 8 ft
volume of a cylinder=pi*r²*h-----> pi*2.5²*8----> 157 ft³
the answer is157 ft³
Answer:
C. 
Step-by-step explanation:
Iterative geometric sequence:

Recursive geometric sequence:

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

And so the answer is C.
Answer:54 minutes
Step-by-step explanation:
9 x 5 = 45 then 45+ the.1 minute from each mile so it would be 9 +45 = 54 minutes
-8k - 8(-8k + 6) = -8k + 64k - 48 = 56k - 48
