The diameter of a bike wheel is 21 inches. If the wheel makes 13 complete rotations , how far does the bike travel?

πd = c

π21 = 65.9734457

c = 66 inches

66 X 13 = 858 inches

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

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
