Hello!
To find the volume of a cone, use the formula: V = 1/3πr²h.
In the photo, the height is 6 units, and the diameter is 8 units. Since the radius is half the diameter, then the radius is 4 units.
V = 1/3π(4)²(6)
V = 1/3(6)(16)π
V = 2(16)π
V = 32π
V = 100.5309... This can be rounded to about 100.5.
Therefore, the volume of this cone, is about 100.5 units³.
