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
Answer:
x = -1
y = -9
Step-by-step explanation:
<u>A</u><u>d</u><u>d</u><u> </u><u>each linear equation:</u>
Sum: 5x = -5
<u>Divide each side by </u><u>5</u><u>:</u>
Quotient: x = -1.
<u>Substitute x = </u><u>-</u><u>1</u><u> into the </u><u>first</u><u> equation:</u>
4(-1) - y = 5
<u>Solve</u><u>:</u>
-4 - y = 5
<u>Add 4 to both sides of the equation:</u>
-y = 9
y = -9.
<u>Check with the second equation:</u>
-1 + -9 = -10.
Correct.
Answer: Two answers: f=-3
f=3
Step-by-step explanation:
3(f-5)=6f-12+3f
3f-15=6f-12+3f
-15+12=6f+3f-3f
F=-3
Answer2
3(f-5)=6f-12+3f
3f-15=6f-12+3f
3f-6f+3f=-12+15
F=3
