Volume of cylinder =
R=8 but h is unknown so unfortunately I can't help you find the volume due to insufficient information
Hello,
A: is an arithmetic sequence: f(n)=3+(n-1)*4
B: is a Fibbonacci's sequence f(n+2)=f(n+1)+f(n), f(1)=4,f(2)=6
C: is a geometric sequence :first term =4 ratio=4
f(n)=4*4^(n-1)=4^n
<span>4 4/8 + 3/4
=4 1/2 + 3/4
=4 2/4 + 3/4
= 5 1/4</span>
If they drive an average of 60 miles per hour the last day it will take them 2.5 hours.
4 hours at 60 miles per hour = 4*60 = 240 miles
6 hours at 65 miles per hour = 6*65 = 390 miles
This is a total of 630 miles. There are 780-630=150 miles left; if they average 60 miles per hour, that would be 150/60 = 2.5 hours.
