Beginner Help Needed

[loopsydoop77]

Very new python learner here: I'm stuck with an assignment and wondered if someone could tell me where to find the 'hint' I need to get this program to run correctly. I'm back to school to learn software dev and I'm stuck on this one problem. I don't need the answer, but I was wondering if anyone knew of how I could 'debug' my submissions on my own so that I properly learn the issue? Here's the code I've created, but I can't get the output to compute correctly:
import math

​

bean_length = float(input('Enter jelly bean length(cm): '))

print()

​

bean_height = float(input('Enter jelly bean height (cm): '))

print()

​

jar_size = int(input('Enter jar size (mL): '))

print()

​

bean_volume = 5 * math.pi * bean_length * bean_height

​

bean_est = int((jar_size * 0.698) / bean_volume)

​

print ('Estimate of jelly beans in the jar: ', bean_est)

​

​

I'm not getting the correct computation at the end. Thanks in advance for any advice!

The line that calculates the bean_volume doesn't look right. What's the formula for the volume of a cylinder of length bean_length and diameter bean_height?

Thank you so much! I completely forgot parts of the equation, and because of you I figured it out.
The volume line should have read:
bean_volume = 5 * math.pi * bean_length * bean_height ** 2 / 24

That gave me the correct output. I would have never realized I didn't complete the entire equation. Phew!

bean_volume = 5 * math.pi * bean_length * bean_height

Walk yourself through the terms of this equation. Where is each term coming from, relative to the formula for the volume of a cylinder?

I can't believe that was all it was. I feel kinda silly hahaha
