Question

What is the height of cylinder with a surface area of 226.08 square meters and a radius of 3 meters? (Use 3.14 for π.)

Answer 1

\[SA = 2 \pi r^2 + 2 \pi r h\]

Answer 2

Here as you want to find h:

\[h = \frac{SA - 2 \pi r^2}{2 \pi r}\]

Answer 3

Does the cylinder have closed ends or open ends?

Answer 4

If the cylinder has open ends the surface area is found from:
\[SA=2\times \pi \times r \times h\]
\[h=\frac{SA}{2\pi r}\]
