Answer:
V = 603.43 cm³
Step-by-step explanation:
V = πr²h
Where r = 4 cm, h = 12 cm
V = 22/7 × 4² × 12
V = 22/7 × 4 × 4 × 12
V = 4224/7
V = 603.43 cm³
Yes it’s a rectangle because the diagonals bisect each other, and they are equal in length.
I believe it would be 3×4x<35
Im guessing you meant improper. This means that the numerator is greater than the denominator. An example is 11/4
