Step-by-step explanation:
The surface area of cylinder is given by the formula:
Where
r is radius ( diameter is 4, so radius is 4/2 = 2)
h is height ( h = 9)
Lets find original surface are:
<u>Halving diameter:</u>
diameter would be 4/2 = 2, so radius would be 2/2 = 1
So, SA would be:
<u>Halving height:</u>
Height is 9, halving would make it 9/2 = 4.5
Now, calculating new SA:
Original SA is ,
Halving diameter makes it
Halving height makes it
So, halving diameter does not have same effect as halving height.
