The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.
If the radius of the base is

and the height is

, then the surface area of the cylinder is

You're given that the area is

and the radius is

, so you have
Answer:
-3-(-7)
when subtracting a negative the signs turn in to addition
-3+(+7)
4
Step-by-step explanation:
Answer:
Step-by-step explanation:
Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.
c first:
and
and
c - 8 = 272 s0
c = 280
For a:
and
and
-34a = 3 so

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.
