Answer:

d = 364 feet

Step-by-step explanation:

Given that,

The pressure at depth d is given by :

$P=13+\dfrac{8}{13}d$

Pressure under water is found to be 237 pounds per square foot

Now, put P = 237 to find d. So,

$237=13+\dfrac{8}{13}d\\\\237-13=13+\dfrac{8}{13}d-13\\\\224=\dfrac{8}{13}d\\\\d=\dfrac{224\times 13}{8}\\\\d=364\ ft$

So, the depth is equal to 364 feet.

Hello!

To find the lateral area you use the equation

$\pi r \sqrt{ h^{2} + r^{2} }$

You put in the values you know and you get 829.4

To find the surface area you use the equation

$\pi r(r+ \sqrt{ h^{2} + r^{2} }$

Put in the values you know and you get 1209.5

The answer is A
