Note: The volume of a cylinder is:
radius² × π × height
First lets work out the volume of Cylinder A:
Volume = 1² × π × 4
= 4π m³
Now lets work out the volume of Cylinder B
Volume = 2² × π × 4
= 16π m³
__________________________________________
Now lets compare the volumes ( Cylinder A : Cylinder B) :
4π : 16π
Lets simplify this by dividing both sides by 4π:
4π : 16π <em>( </em>÷ <em>4π)</em>
----> 1 : 4

Answer:
38 seconds
Step-by-step explanation:
just take 2x7 for the elevator taking the time to reach your floor which is 14 seconds. then just add on the additional time that all the passengers take to get off the elevator as it's only counting the time since it starts moving. that is 12x2=24. now just add 24+14 and you get your answer of 38
