Answer:
See Below
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.
Answer:
Bucket 2
Step-by-step explanation:
Bucket 1 = 4700ml
Bucket 2 = 4.8l
Bucket 3 = 3880ml
Bucket 4 = 4.71 l
Convert holding capacity of bucket 1 and bucket 3 into liters
1 liter = 1000 milliliter
Bucket 1 = 4700ml
4700ml = 4.7l
Bucket 3 = 3880ml
3880ml = 3.88l
Therefore,
Bucket 1 = 4.7l
Bucket 2 = 4.8l
Bucket 3 = 3.88l
Bucket 4 = 4.71 l
The bucket closest to 5liters is bucket 2 with a holding capacity of 4.8 liters
Hi!
I believe the answer is D , because the common denominator is 12 .
3 times 4=12
4 times 3=12
2 times 6= 12
You multiply each fraction by 12/1 .
Hope it helps and have a wonderful day !
