IrinaVladis [17]

Answer:

The volume of the shaded figure is 252π feet³ ⇒ 1st answer

Step-by-step explanation:

* <em>Lets revise how to find the volume of the sphere</em>

- The volume of any sphere is \frac{4}{3}\pi r^{3}, where

  r is the radius of the sphere

- There is a large sphere of diameter 12 feet

- The diameter of the sphere is twice its radius

∵ The length of the diameter is 12 feet

∴ The length of the radius = \frac{1}{2}*12=6 feet

- There is a smaller sphere with a radius of 3 feet

- The smaller sphere is cut out of the center of the larger sphere

- <em>The volume of the shaded part is the difference between the </em>

<em>   volumes of the larger sphere and the smaller sphere</em>

* <em>Lets find the volume of each sphere</em>

- The volume of the larger sphere:

   V larger = \frac{4}{3}\pi (6)^{3} = 288π feet³

- The volume of the smaller sphere:

   V smaller = \frac{4}{3}\pi (3)^{3} = 36π feet³

∴ The volume of the shaded figure = 288π - 36π = 252π feet³

* The volume of the shaded figure is 252π feet³
