A. 502.4 cubic centimeters
B. 1256 cubic centimeters
C. 2009.6 cubic centimeters

3. What effect does doubling the radius of a cylinder have on the volume of the cylinder?
A. The volume is doubled.**
B. The volume is quadrupled.
C. The volume is halved.
D. The volume is multiplied by one-fourth

Need help!

1. pi r^2 h = v

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

3, NO!!!! pi R * R * h

R*R is not R
2 * 2 is not 2

the answers?

2. 3*16*10 or 30*15 about 450

Hey are you just guessing?

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

Would #1 be 0.8?

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