If sin yº = a/6 and tan yº = a/b what is the value of cos yº?

answer:cos y = b/6.

If sin = O/H, then O = a and H = 6.

If tan = O/A, then A = b.

Therefore, if cos = A/H then

cos y = b/6

Hope this helped !!!

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
