Answer:

92.9 cm squared

Explanation:

The surface area of a cylinder is denoted by: A=2\pi r^2+2\pi rh, where r is the radius and h is the height.

Here, we know the diameter is 3.4 cm, so the radius, which is half the diameter, is r = 3.4 / 2 = 1.7 cm. The height is 7. Plug these in:

A=2\pi r^2+2\pi rh

A=2\pi *1.7^2+2\pi *1.7*7=29.58\pi

29.58π ≈ 92.9 cm squared
