Answer:
20
Step-by-step explanation:
i think, dont trust me tho
Focus on triangles DFC and DFE:
- They are both right triangles because DF is perpendicular to EC
- DC=DE
- DF is a common side
So, the two triangles are congruent. It follows that CF=FE, and in particular

And since x=3, the length of EF is

<em>C. A sphere with radius 0.6 inches.</em>
<u><em>Here is why:</em></u>
The equation for the volume of a sphere is:

We can plug in and solve.

We will multiply everything but leave the 3 to divide later.
So...

Divide by 3.

0.288π
