aleksley [76]

Answer:

754 inches³

Step-by-step explanation:

The equation for the volume of a cylinder is V = π*r²*h.

So you have d = 8 (meaning r = 4) and h = 15. Substitute in those values into the equation and you'll get V = π*4²*15 = 753.98, which rounds to 754 inches³

Answer:

\displaystyle \frac{\pi}{6}

Explanation:

According to the unit circle, \displaystyle \frac{\pi}{3} and \displaystyle \frac{\pi}{6} are the radian measures you are looking for because all <em>y-coordinates</em> are associated with the <em>sine</em> function, so when evaluating, you will arrive at this:

\displaystyle \boxed{\frac{\pi}{3}} = \frac{\pi}{3} - \frac{\pi}{6}
