5.21 + 0.6 - (0.27 / 3) I assume this is the right equation
5.21 + 0.6 = 5.81
0.27 / 3 = 0.09
5.81 - 0.09 = 5.72
Since r = h, we can substitute that into the equation
<span>V = pi * r^2 * r = pi * r^3 </span>
<span>Since we know the volume, we can put that in too. </span>
<span>64 pi = pi * r^3 now let's divide both sides by pi. </span>
<span>64 pi/pi = pi * r^3/pi </span>
<span>64 = r^3 </span>
<span>cuberoot(64) = r </span>
<span>cuberoot (2^6 )=r </span>
<span>4 = r</span>
For lines to be perpendicular they would need to have opposite slopes, so for a slope of -3/7 the slope of a perpendicular line would be 7/3
