9x^2 -6x +1+12=0
9x^2 -6x +13=0
factorise
(3x-1)(3x-1) =0
so, x= 1/3
For this case we have that the figure shown is composed of a cylinder and a cone.
We have that the volume of a cylinder is given by:

Where:
A: It's the radio
h: It's the height
Substituting the values:

On the other hand, the volume of a cone is given by:

Where:
A: It's the radio
h: It's the height
Substituting the values:

Then, the total volume is:

Taking
, we have to:

Answer:
Option D
The value of csc theta from the given diagram is 15/12
<h3>Application of SOH CAH TOA</h3>
The given triangle is right angle triangle. According to trigonometry identity
csc theta = 1/sintheta
Given
- Opposite = 12
- Hypotenuse = r
sin theta = 12/r
Determine the value of r
r² = 9² + 12²
r² = 81 + 144
r² = 225
r = 15
sin theta = 12/15
Determine the value of csc theta
csc theta = 15/12
Hence the value of csc theta from the given diagram is 15/12
