Mathematics
1 answer:
djyliett [7]3 years ago

Answer:

Look at the unfolded cylinder down: it's consisted of a rectangle and 2 circles. so to find the surface area of the cylinder we should find the areas of the rectangle and the 2 circles.

1) A of 2 circles = 2(πr^{2}) = 2πr^{2}

2) A of rectangle = base x height (or length x width) = bh

but the if we fold the rectangle? what will happen?

the base will go around the circle, this means that the base is equal to the circle circumference, which is 2πr.

Therefore, A of rectangle = 2πrh

3) Surface area of cylinder =  2πr^{2} + 2πrh

   simplify more and take the common factor 2πr:

    = 2πr (r+h)

Find the slope of the line:<br> 5x+3y=6
natka813 [3]
To get the result we have to transform given formula into y=ax+b form.
Lets do this
5x+3y=6   /-5x  (subtract 5x both sides)
3y=-5x+6  /:3  (divide both sides by 3)
y=-\frac{5}{3} x+6
In form y=ax+b we know that a is slope and b is y intersect. We can read from our transformed equation that slope a=-\frac{5}{3}and its the result
