Step-by-step explanation:

The lateral surface area of a cylinder is calculated using:

[tex]L.S.A = 2\pi \: rh[/tex]

We have that the lateral surface area is about, 80 square inches.

Assuming the radius is 10 inches, then we substitute r=10, π=3.14 and solve for h.

[tex] 80 = 2 \times 3.14 \times 10h[/tex]

We solve for h to get:

[tex]h = \frac{80}{2 \times 3.14 \times 10 } = \frac{4}{3.14} [/tex]

[tex]h = 1.3inches[/tex]
