Question

What is the volume of a circular cylinder with a base diameter of 6 m and a height of 5 m?

Answer 1

For this case we have that by definition the volume of a cylinder is:
 V = ((pi) * (r ^ 2)) * (h).
 Where
 r: radio
 h: height.
 Also we have
 r: d / 2
 Where,
 d: diameter.
 Substituting we have:
 V = ((pi) * ((d / 2) ^ 2)) * (h).
 V = (pi) * (((6) / 2) ^ 2) * (5).
 V = 45pi m ^ 3
 Answer:
 The volume of a circular cylinder is:
 V = 45pi m ^ 3
