$\sf\huge\underline\red{SOLUTION:}$

Use formula:

$\sf{V = \pi(\frac{d}{2})^2h}$

Solving for diameter:

$\sf d = 2 \times \sqrt{ \frac{V}{\pi h} } \\ \sf = 2 \times \sqrt{ \frac{40}{\pi \times 1800} } \approx0.16821 \\ = \sf \large\boxed{\sf{\green{d = 0.17}}}$

$\sf\huge\underline\red{FINAL \: ANSWER}$

$\large\boxed{\sf{\green{d=0.17}}}$

Answer:

$28\sqrt{3}$

Step-by-step explanation:

The area of the big triangle is 1/2 b h = 1/2*6*(12^2 = 6^2 + x^2)

that ends up being $\sqrt{108} = 36\sqrt{3}$

the small triangle are needs to be subtracted....

$\frac{\left(4\cdot \:sin\left(90\right)\right)}{sin\left(30\right)}$ that is the length of the unknown side...

1/2 B * h of that triangle get you to $8\sqrt{3}$

just subtract the two areas
