1. pi r^2 h = v
v = pi (12.5)^2 h = 375
3*150 h = 375
h = less than 1
disagree with you

2. 3*16*10 or 30*15 about 450
Hey are you just guessing?
Answered by Damon
3, NO!!!! pi R * R * h
R*R is not R
2 * 2 is not 2

I wasn't quite sure on my answers. So I gave my best guess

Would #1 be 0.8?
Answered by panda
For #2, I tried using a calculator but I guess I did the math wrong. Would it be 502.4?
