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
