The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²
<h3 /><h3>How to find the surface area of a cylinder?</h3>
Surface area of a cylinder = 2πr(r + h)
Therefore,
radius is tripled = 3(7) = 21 inches
height is shrunk half its size = 17 / 2 = 8.5 inches
Therefore,
surface area = 2 × 3.14 × 21 (21 + 8.5)
surface area = 131.88(29.5)
surface area = 3890.46 inches²

X would equal 0 because u would use the distribution 3x+3=3x+3 and then subtract three from the three on the other side and then subtract 3x from 3x and then 0
Answer:
Other number is 23
Step-by-step explanation:
Let the two numbers be x and y.
We have given that average of x and y is 17.
i.e 
if one of the number is 11,
Then , 
or (11 + y)/2 = 17
or 11 + y = 34
or y = 34 - 11
or y = 23
