Question

The large sphere has a diameter of 20 feet.

Answer 1

Answer:

The volume of the sphere is 4187 cubic feet, approximately.

Step-by-step explanation:

The volume of a spherer is defined as

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

Where $r$ is the radius and $\pi \approx 3.14$

According to the proble, the diameter is 20 feet. By definition of radius,

$r=\frac{d}{2}=\frac{20ft}{2} =10ft$

Replacing the radius in the volume formula

$V=\frac{4}{3} \pi (10)^{3}$

$V=4,187 \ ft^{3}$

Therefore, the volume of the sphere is 4187 cubic feet, approximately.
