Fthe plane intersects the cylinder horizontally, the cross section is if the plane intersects the cylinder slanted between horizontal and vertical, the cross section is if the plane intersects the cylinder vertically through the cylinder, the cross section is if the plane intersects the cylinder vertically along an edge of the cylinder, the cross section is

5y

step-by-step explanation:

13.46

step-by-step explanation:

16.80 x .20 = 13.46

true

step-by-step explanation:

intersecting chords are just lines that intersect. so a line is equal to 180 degrees, so when it is intersected by another chord, then it create supplementary angles, and because the lines cross, vertical angels are also formed.

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
