Your octagon has a central angle of 360 deg. Since you're speaking of an octagon, which implies that the octagon is made up of eight triangles, divide 360 deg by 8 to obtain the measure of each minor arc formed.
By definition, the volume of a cone is given by:
V = (1/3) * (pi) * (r ^ 2) * (h)
Where,
r: cone radius
h: height of the cone
Substituting values:
V = (1/3) * (3.14) * ((8/2) ^ 2) * (9)
V = 150.72 cm ^ 3
Answer:
this paper cone cup can hold:
V = 150.72 cm ^ 3
