A right circular cone is made from of a radius of 5 cm, a central angle of 216 degrees, what is the volume of the cone in cubic cm?
Added by Bradley M.
Step 1
We know that the central angle is 216 degrees, which means that the angle at the apex of the cone is half of that, or 108 degrees. We can use trigonometry to find the height: tan(108) = height/5 height = 5tan(108) ≈ 10.2 cm Now that we have the height, we can Show more…
