Answer:
B) A < 0
Step-by-step explanation:
I had the same question, and got it right.
Answer: 9.98 meters
Step-by-step explanation:
Angle = 12°
Displacement = 48 m
The height, or displacement in the y-axis will be equal to the opposite cathetus of a triangle rectangle where the hypotenuse is the displacement, then we can find that the displacement in the y-axis is:
h = sin(12°)*48m = 9.98m
Answer:
A. 16.8 in³
B. 28.3 m³
C. 65.4 in³
Step-by-step explanation:
The volume of a cone is given as:
V = ⅓ * pi * r² * h
Where r = radius of base of cone
h = height of cone
A. Radius = 2 inches, height = 4 inches
It's volume is:
V = ⅓ * pi * 2² * 4
V = 16.8 in³
B. Diameter of 6 m, and a height of 3 m
It's diameter is 6 m, therefore, it's radius is:
r = d / 2 = 6 / 2 = 3 m
It's volume is:
V = ⅓ * pi * 3² * 3
V = 28.3 m³
C. Diameter of 5 in, and a height of 10 in
It's diameter is 5 in, therefore, it's radius is:
r = d / 2 = 5 / 2 = 2.5 m
It's volume is:
V = ⅓ * pi * 2.5² * 10
V = 65.4 in³
