Answer:
The volume of the cone is ≈ 301.59.
Step-by-step explanation:
The equation to use
. You plug in 6 as the radius (r) and 8 as the height (h).
Are we solving for h?
V=πr²h+r²h
V=h(πr²+r²)
V/(πr²+r²) = h
80p=pr^2+p(2r)^2
80p=pr^2+4pr^2
80=r^2+4r^2
80=5r^2
16=r^2
r=4 for the smaller circle´s radius, and 8 is the larger circle´s radius.
