Cannot. If you do not know the angle of the cone, you cannot determine its height.
The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.
108.4 square feet
Your diameter is double the radius. So the diameter is 6
The base radius ( or diameter) and the height
The radius IS given, since height of hemisphere = radius of hemisphere!
1319.47 meters squared
Around 77 cm2. volume=(one third)(pi)(radius squared)(height)
Radius of cone = 19/2 = 9.5 mm Volume = (1/3) PI r^2 h, where r is the radius and h is the height, We need to know the height of the cone to find its volume.
The volume of a cone is base×height÷3base×height÷3=144×π×10÷3base×height÷3=1440π÷3
87766.14 mm cubed. Radius squared times pi find the area of the base. Then, we take it times the height (77) and since its a cone we divide by 3.
Measure it.
It depends on what the cone looks like.
