Answer: second option.
Step-by-step explanation:
You must apply 
Then, given the right triangle and the angle D, the opposite side and the hypotenuse of the triangle are the following:

Therefore, when you substitute values, you have:

Reduce the fraction, then you obtain:

Answer:
C.
Step-by-step explanation:
The answer would be 29 because 9 + 36 = 45 - 16 equals 28

Answer:
563.5 cm³
Step-by-step explanation:
Use the formula for the volume of a cone:
V = (1/3)πr²h
Recognize that the radius is half the diameter:
r = (11.9 cm)/2 = 5.95 cm
V = (1/3)π(5.95 cm)²(15.2 cm) ≈ 563.516 cm³
The volume of the cone is about 563.5 cm³.

<em>Additional comment</em>
If you use 3.14 for the value of π, then the result will be 563.2 cm³.
For long division, you would put 700 in the middle, since the fraction would be 700/21. Then you would figure out how many times 21 goes into 700. Then you would subtract 700 by the amount it would be before it went above 700 by multiplying it by 21. Then, if it is not able to go into 700 fully, you would put a decimal and bring a 0 down.
