Answer:
V = 3078.76 in³
Step-by-step explanation:
To find the volume of a cylinder, use this formula:
V = πr²h
- V = volume
- r = radius
- h = height
Plug in the values you know.
V = π(7)²(20)
First let's evaluate the exponent.
7² = 49
V = π(49)(20)
Now let's multiply.
49 • π = 153.938
153.938 • 20 ≈ 3078.76
V = 3078.76 in³
This is your answer.
Hope this helps!
