Answer:

C.13

Step-by-step explanation:

D is a midpoint, which means that AD=DB= 1/2 AB = 1/2 (24) = 12

Using Pythagorean theorem we know that CD^2+DB^2=CB^2

That means that 5^2+12^2=CB^2

25+144=169

169=13^2

CB=13

a=CB=13

The volume of a spherical tank is 790.272 pie cubic feet what is the diameter of the container

pochemuha

Answer:

The diameter is 13.88 feet.

Step-by-step explanation:

1. The formula for calculate the volume of a sphere is:

$V=\frac{3}{4}(r^{3}\pi)$

Where $r$ is the radius.

2. The diameter is:

$D=2r$

3. So, you must solve for the radius in the first equation:

$r=\sqrt[3]{\frac{4V}{3\pi}}$

$r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft$

4. Then, the diameter is:

$D=2(6.94ft)\\D=13.88ft$
