If the radius of a cylinder is doubled and the height is tripled, what happens to the volume?
1 answer:
Answer:
B
Step-by-step explanation:
Original volume = pi * r^2 * h
New r = 2*r
New h = 3*h
New Volume = pi * (2r)^2 *3*h
New Volume = pi * 4r^2 * 3 *h
New Volume = 4*3 * pi * r^2 + h
Conclusion
The New Volume = 12* the original volume

Step-by-step explanation:
41 , 35,30 , X , Y ,15
Number of data's = 6. So, median will be the average of 
. 3 and 4th term
Median = 
30 + X = 25*2
30 + X = 50
X = 50 - 30
X = 20
Mode is 15
So, Y = 15
