Question

Each cracker in the stack has a diameter of 2 inches. The height of the stack is 7.5 inches. What is the volume of the stack? A) 18.75 in3 B) 23.55 in3 C) 35.95 in3 D) 47.10 in3

Answer 1

For this case, we can model the problem as a cylinder.
 The volume of a cylinder by definition is given by:
 V = (pi) * (r ^ 2) * (h)
 Where,
 r: cylinder radius
 h: height
 Substituting values:
 V = (3.14) * ((2/2) ^ 2) * (7.5)
 V = 23.55 in ^ 3
 Answer:
 the volume of the stack is:
 B) 23.55 in3
