800 + 60 + 3 + 0.1 + 0.04 + 0.001
That's 863.141 in expanded form.
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
Replace n with 13 and simplify
an = 84+(n-1)*(-6)
a13 = 84+(13-1)*(-6)
a13 = 84+(12)*(-6)
a13 = 84+(-72)
a13 = 84-72
a13 = 12
Answer: Choice A) 12
B. sometimes
sometimes it’s a line and sometimes it’s dashed depending on the less than great than sign
You need to get x by itself. Add 6 to both sides.
x = 14
