The expression that represents the volume of the given cone, in cubic units is 2/3 πx³.
<h3>How to calculate the volume of the cone?</h3>
The volume of a cone with radius 'r' and slant height 'h' is
V = 1/3 π r² h
Unit: cubic units
<h3>Calculation:</h3>
The given cone has radius r = x and height h = 2x
Then, the volume of the cone is calculated by
V = 1/3 π r² h
= 1/3 π x² (2x)
= 2/3 π x³ cubic units
Therefore, the volume of the given cone is V = 2/3 π x³ cubic units.
So, option A is correct.

Question: What expression represents the volume of the cone, in cubic units?
A) 2/3 πx³
B) 4/3 πx²
C) 2πx³
D) 4πx³
Answer:
Please find the solution in the image attached below.
Step-by-step explanation:
Tcos60 -2T sin(90-theta) = 0
Tcos60 = 2T(cos theta)
cos 60 = 2cos theta
cos60 = 2cos theta
1/4 = cos theta
theta = 75.5
So the angle to the vertical = 90-75.5 = 14.5
S
Resolving perpendicular
Tsin60 + 2Tsin75.5 - 2g = 0
T(sin 60 + 2sin75.5) = 2g
T = 19.6/sin 60 + 2sin75.5
T = 19.6/1.936 + 0.866
T = 19.6/2.802 = 7.0N
Hope this helps!
