The height of the cone with a volume of 1/18π ft³ is: 1.5 ft.
<h3>What is the Volume of a Cone?</h3>
Volume of a cone = 1/3πr²h, where, h = height of cone, and r = radius of the cone.
Given the following:
- Volume = 1/18 π ft³
- Diameter = 2/3 ft
- Radius = (2/3)/2 = 1/3 ft
- Height (h) = ?
Plug in the values into the volume formula:
1/18π = 1/3π(1/3)²h
1/18π = 1/3π(1/9)h
1/18π = (πh)/27
Divide both sides by π
1/18 = h/27
Cross multiply
27 = 18h
27/18 = h
h = 1.5
Therefore, the height of the cone with a volume of 1/18π ft³ is: 1.5 ft.

Answer:
what is the question exactly??
Step-by-step explanation:
The sum of the measures of the angles of a polygon of n sides is 180(n - 2).
Set that expression equal to 1800 and solve for n, the number of sides.
180(n - 2) = 1800
Divide both sides by 180
n - 2 = 10
Add 2 to both sides
n = 12
The polygon has 10 sides.
m<1 + m<2 = 180°
m<3 + m<4 = 180°
Because they are both equal to 180°, you can set them equal to each other.
m<1 + m<2 = m<3 + m<4
Angles 1 and 4 are congruent (equal), so we can subtract them from each side to get:
m<2 = m<3
