The surface

can be parameterized by

where

and

. Then the surface integral can be computed with

Answer:
56.556 square inches
Step-by-step explanation:
Surface area of an open cylindrical pipe is = πdh
3.142 × 1 × 18 = 56.556
Answer: A) 0.1
Explanation:
<span>Each of the integers in the first set could be combined with any from the second set, giving a total of 4 x 5 = 20 possible pairs.Of these the combinations that could give a sum of 23 are (5 + 18), and (9 + 14)<span>This means that the probability of getting a sum of 23 is 2/20 = 1/10</span></span>
Just subsitute 8 for n
1/2(8)^2-1/2(8)
1/2(64)-4
32-4
28
D
2(4x-3)-7(x+1) first distribute
8x-6-7x+7 then combine the x's
<u>x+13 </u>
