In units squared, what is the surface area of a cylinder that has a radius of 7 and a height of 8? Make sure to use 3.14 for \pi.

d

step-by-step explanation:

i used the pitagoras theoreme

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

step-by-step explanation:

gym b charges $1.05 less per hour than gym a.
