The answer is option c- 68°
Answer:

Step-by-step explanation:
The volume of a cone is given as:

where r = radius
h = height of cone
The height of the cone is 17.7 cm and its base radius is 7.9 cm (diameter is 15.8 cm).
Its volume is:

Answer:
The angles are adjacent and x=100
You are shown an ordered pair with an x-coordinate of -5, so replace x with -5 and solve for y.
-3x + 7y = 5x + 2y
-3(-5) + 7y = 5(-5) + 2y
15 + 7y = -25 + 2y
5y = -40
y = -8
Answer:
1. Answer is D) (1, -3)
2. Answers are B) (0,4) and D) (4,-14)
Step-by-step explanation:
You can substitute the values of x and y from the options in the equations and hence, you'll get the answers.
