Question

The total area of a cylinder is 100(pie). If r=h, find r.

Answer 1

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

Answer 2

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

Answer 3

So the answer is: \[4xr ^{2}\]

Answer 4

?

Answer 5

solve for "r"

Answer 6

the question says, "find r"
