The volume of a cone is V = 1/3 pi r^2 h
h = 8
pi = 3.14
V =471.24
r = ??? 
d = ???

471.24 = 3.14 * 8 * r^2
471.24 = 25.12 * r^2
471.24 / 25.12 = r^2
18.76 = r^2
r = sqrt(18.76)
r = 4.312

The diameter is 2*4.312 = 4.624 in. <<<<<==== answer.

 If arc AB = 70°, how many degrees are in ∠ ADB?
tankabanditka [31]

If D is the center of the circle, ∠ADB = 70°, as that is where the arc gets its measure.

If D is on the circle and not on the arc, ∠ADB = 35°, half the measure of the arc's central angle.

If D is on arc AB, then ∠ADB = 145°, half the measure of the corresponding central angle.

If D is inside or outside the circle (and not one of the above), we need to know more about the measures of arcs intercepted by lines AD and BD.
