Question

Please Help me!!!
What is the volume of a cylinder with a radius of 4 and a height of 9?
-----
A. 13π
B. 36π
C. 72π
D. 144π

Answer 1

Answer: D

Explanation:
Area of cross section= π x 4^2 = 16π
Volume = 16π x 9 = 144π

Answer 2

Answer:

144.1π cubic units

Step-by-step explanation:

Utilize the volume formula V = (pi)r^2h, where r is the radius and h is the height:

Here V = (pi)(4^2)(9)  ≈  (22/7)(16)(9) ≈ 144.1π
