Answer: 2 πr^2 h Step-by-step explanation: volume of the cylinder = πr^2 h when it’s radius doubled and height becomes half =π(2r)^2 ×h/2 =π 4r^2 ×h/2 = π 2r^2 ×h =2 (πr^2 h) Reply
Answer:
2 πr^2 h
Step-by-step explanation:
volume of the cylinder = πr^2 h
when it’s radius doubled and height becomes half
=π(2r)^2 ×h/2
=π 4r^2 ×h/2
= π 2r^2 ×h
=2 (πr^2 h)
Answer:
4πr square h divided by 2
