Answer 1

Answer:

Step-by-step explanation:

A) either radius or diameter and height

V = πR²h or πD²h/4

B) Radius is half a diameter, R = 4 cm

C) Rather depends on how they are put together.

Placing the rectangular faces touching would make a cylinder

D) V = 3.14(4²)(2) = 100.48  ≈ 100 cm³

E) divide by 2

i.e. V = ½πR²h

F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³
