PLEASE HELP WITH MATH. BEST GETS BRAINLIEST.Celina is buying fabric scraps to make koozies for her glasses. Each glass is cylindrical with a diameter of 3 inches and a height of 4 inches. The koozies will cover only the sides of the glasses. What is the amount of fabric she will use? What does this amount represent? Use 3.14 for pi. Show your work.
Answers
The surface area of the sides is equal to the perimeter of the base times the height of the cylinder. It makes sense logically because the sides are basically the perimeter of the base, raised all the way up along the cylinder.
SA = perimeter x height
SA = pi x diameter x height
SA = 3.14 x 3in x 4in
SA = 37.68 in^2
She will use 37.68 square inches of fabric.

Answer:
The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5
Step-by-step explanation:
Given line equation as :
3 y = 2 x - 1
Or, y = x -
So , The equation is in the form of y = m x + c
Where m is the slope of the line
∴ satisfying the condition
Slope of given line is m =
Now , ∵ The other line is perpendicular to this line and passes through point ( - 1 , 4 )
Let , Slope of other line = M
∴ for perpendicular line condition , products of the slope = - 1
I.e m × M = - 1
Or , M = -
Or M = -
Or M = -
Thus The equation of line with slope M and passing through points ( - 1 , 4 ) is
or, (x + 1)[/tex]
or, 2y - 8 = - 3 (x +1)
Or, 2y - 8 = - 3x - 3
or 2y = - 3x - 3 + 8
∴ 2y = -3x + 5
Hence The equation of line perpendicular to given line and passes through points ( - 1 , 4 ) is 2y = -3x + 5 Answer

Answer:
D.252
Step-by-step explanation:
In this question, We have to find which rotation about its center will carry a regular decagon onto itself?
A decagon : 10 sided polygon
As we know, a full rotation can be 360°.
For a decagon: 360/10 =36
For a decagon, any multiple of 36 can map onto itself.
In our options only 252 is the multiple of 36.
So, correct answer is option D252
