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:<em> 44 matches</em>
Step-by-step explanation:
<em>Let's take the given information</em>
<em>They won 37 matches</em>
<em>1/9th of their matches resulted in a draw</em>
<em>1/9 out of 90 is 9</em>
<em>You can take 90/9 and you will get 9</em>
<em>Now let us add 37+9 and you get 47</em>
<em>Now take 90-47</em>
<em>44 Matches lost</em>
<em>22/45 or 44/90</em>

Yes, 6 over 2 equals to 3.
6 = 2 x 3
6/2 = (2 x 3)/2 = 3
Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.
