Answer:
251.2 unit²
Step-by-step explanation:
Radius = 4 unit, height = 5 unit
Volume of cylinder = pi r² h
Where pi(#) = 3.14
Volume = # × 4² × 5
Volume = # × 16 × 5
Volume = 80# unit²
Volume = 80 × 3.14
Volume = 251.2 unit²

Answer: 80 pi
Step-by-step explanation: the formula for a cylinder is
V = pi r ^2 (h)
with inputting 4 for radius and 5 for height, this will result with 251.33.
251.33/3.14159
= 80 pi
