## anonymous 3 years ago The total area of a cylinder is 100(pie). If r=h, find r.

1. anonymous

The formula to find the total area is L.A + (2)Area of the base.

2. anonymous

total area of cylinder = area of top + area of bottom + area of curved surface $100\pi=\pi r^2+\pi r^2+2\pi rh\\ 100\pi=4\pi r^2$

3. anonymous

So the answer is: $4xr ^{2}$

4. anonymous

?

5. anonymous

solve for "r"

6. anonymous

the question says, "find r"
