we know that
diameter of the base of a cylindrical can= 4 in----------> r=2 in
h=6.5 in
[surface area]=2*[pi*r²]+[2*pi*r*h]
then
[surface area]=2*[pi*2²]+[2*pi*2*6.5]=[ 25.13 ]+[ 81.68 ]=106.81 in²
the answer is 106.8 in²
Since an <em>octagon</em> has 8 equal sides, multiply the given 35ft length by 8 to get total perimeter.

Answer:
a. 10, 16
b. 211, 311
c. 10 , 12.5
d. -13, -22
Step-by-step explanation:
In an arithmetic sequence, there is a constant difference, which is the difference between a term and the previous term. We find the constant different for each sequence, and we add it to the second term to find the third term. Then we add the constant difference to the third term to find the fourth term.
a.
4 - (-2) = 6
3rd term: 4 + 6 = 10
4th term: 10 + 6 = 16
b.
111 - 11 = 100
3rd term: 111 + 100 = 211
4th term: 211 + 100 = 311
c.
7.5 - 5 = 2.5
3rd term: 7.5 + 2.5 = 10
4th term: 10 + 2.5 = 12.5
d.
-4 - 5 = -9
3rd term: -4 + (-9) = -13
4th term: -13 + (-9) = -22
