11.25. Because both segments are chords and the lines extending from the center are congruent, the chords are congruent. Also, that answer's the one that makes the most sense out of your options.
By definition, the volume of a cone is given by:

Where,
r: cone circular base radius
h: height of the cone
Substituting values we have:

Rewriting the equation we have:


Answer:
An expression that represents the volume of the cone, in cubic units is:

Note: rewrite the options again.
Step-by-step explanation:
with $4,000 invested, Jake has
8% × $4,000 = $320 annually.
in order to have annual interest $628, he has to get more interest $(628-320) = $308.
