The formula for the surface area of a cylinder is:

Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):

Simplify:

Subtract 1413 to both sides:

Divide 94.2 to both sides:

So the height is approximately 45 millimeters.
Step-by-step explanation:
x= Number of small pages
y= Number of full pages
1 x + 1 y = 21 .............1
Total words
1200 x + 1500 y = 27000 .............2
Eliminate y
multiply (1)by -1500
Multiply (2) by 1
-1500 x -1500 y = -31500
1200 x + 1500 y = 27000
Add the two equations
-300 x = -4500
/ -300
x = 15
plug value of x in (1)
1 x + 1 y = 21
15 + y = 21
y = 21 -15
y = 6
y = 6
x= 15 Number of small pages
y= 6 Number of full pages
If you would like to simplify the expression 22 * (32 - 42), you can do this using the following step:
22 * (32 - 42<span>) = 22 * (-10) = - 22 * 10 = - 220
</span>
The correct result would be - 220.
