So, to find the volume of just the cement part, you need to find the volume of the whole shape, then find the volume of the garden. then subtract them to find the volume of just the cement sidewalk.

volume of garden: 16 x 6 x 1  (l x w x h)= 96 ft3

volume of whole:  length=16+4+4=24, width=6+4+4=14, height=1
you have to add 4 to each sides of the length and width to get the entire length.
 volume of whole=24 x 14 x 1=336 ft3

now subt.

336-90=246 ft3 would be the volume of the cement walkway.

If StartFraction pi Over 2 EndFraction less than t less than pi ​, which of the following is​ true?
oksian1 [2.3K]

Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

\frac{\pi }{2} < t

if we apply the cosine function in the relation we get:

cos\frac{\pi }{2}

-1

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

cotan\frac{\pi }{2}

0

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0
