H = (S - 2*(3.14)*r squared) / 2*3.14*r

the formula for surface area of a solid cylinder

gotta have 2 of the variables to get the third

X3 this it

[Charles]

It's "C" unless "D" is all of the above!

Bill you're making my head hurt.

I thought this was an English speaking site?

uuuuuuhhhhhhhh, no!

The equation is the surface area of a cylinder (think coke can). Area of the top (pi*r^2) and bottom (pi*r^2) plus the area of the side which is the circumfrance of the circle (2*pi*r) times the height (h). Gives you 2*(pi*r^2)+(2*pi*r*h)=S. To solve this in terms of variables S-(2*pi*r^2)=(2*pi*r*h). This equals [S-(2*pi*r^2)]/(2*pi*r) = H.

In order to get a numerical answer you would need to have two of the variables and you can find the third. If the question does not give any values, leave the answer like this.

2 + 2 = fish!!

Thanks alot fella's... I hate college algebra.

[ArcherAG 93]

I'll have to pass on this one....

And while we are solving problems that appear to be written in Latin or ancient Greek, how about solving a few others. First, what makes a woman think the way she does? Secondly, how do you create world peace?

Have fun with this one!

I guess I am to old.. that stuff makes my head hurt!

I'm going to say around 143" and maybe 4 1/2.

Thanks alot fella's... I hate college algebra.

Algebra is not bad- college calculus and differential equations kicked my butt.

I took diff eq at night at a college I was attending as part of my '7-year plan' and it as taught by a Greek guy who was a mathematician at Bell Laboratories research center. He could see the confused and dazed looks in most of our faces. I'll never forget, he ended each class with a smile and the statement, "Remember, always have FUN with differential equations".

aaaahhhhhhhhh
