It would help to find the surface area now, double the dimensions, find the new surface area, and compare.
The surface area of a cylinder is:
2 * pi * r^2 + 2 * pi * r * h
So, the surface area is:
2 * pi * 64 + 2 * pi * 4 = 136 pi
Double the dimensions:
2 * pi * 256 + 2 * pi * 16 = 544 pi
544 pi divided by 136 pi = 4
So, the answer is 4.
Answer:
C
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis. At this point on the x- axis the y- coordinate is zero.
To find the x- intercept let y = 0 in the equation and solve for x, that is
5x - 2 = 0 ( add 2 to both sides )
5x = 2 ( divide both sides by 5 )
x =
← x- intercept
coordinates of x- intercept are (
, 0 ) → C
