We are going to need to know the formula for the lateral surface area and volume of a cylinder in order to find our answers. Below are the equations:

A_L = 2 \pi r h

V = \pi r^2 h

  • h is the height
  • r is the radius

Using these formulas, we can solve these problems.

A_L = 2 (3.14)(48.9) (84.3) \approx \boxed{25887.856}

V = (3.14) (48.9)^2 (84.3) \approx \boxed{632958.069}
