A cylinder has a diameter of 5 centimeters and a height of 50 millimeters. Which of the following steps should be done first in order to find the surface area of the cylinder?

convert the diameter and the height to the same unit
determine the radius and multiply by 2
calculate the circumference of the circle
multiply the circumference of the circle by the height of the cylinder

B determine the radius and multiply by 2pi

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
