Answer 1

The volume of a cylinder is given by:
 V = pi * r ^ 2 * h
 Where,
 h: height
 r: Radius
 Substituting the values we have:
 V = pi * (3) ^ 2 * (8)
 Rewriting:
 V = pi * (9) * (8)
 V = 72pi cubic units
 Answer:
 V = 72pi cubic units

Answer 2

Volume of a Cylinder is given by: 
V=π(r^2)(h)
use: π=3.14

Substituting;
V=(3.14)(3^2)(8)
V= 226.08 cubic units
