Answer:
Step-by-step explanation:
The formula for the surface area of a cylinder is:
And we want to solve for the height h.
First, subtract 
from both sides. This yields:
Now, divide both sides by 
. This yields:
And we're done!
The slope is the number in front of the x. In this equation it is 1.
Pythagorean Theorem
a² + b² = c²
c = 13
a = 4
(Missing side) = b
4² + b² = 13²
16 + b² = 169
16 - 16
169 - 16 = 153
Square Root of 153 = 12.369
b = 12.369
The missing side is 12.369 (rounded to 12 as a whole number)
She missed 3 questions,
11/100 equals x/26
^set up this proportion
you get 286 equals 100x
and x equals 2.86
round this to 3 questions
to check your work, do 23/26
