First, we need to figure out the radius of the base of the cone. Since the circumference of the base is 18.5 cm, we can use the formula for the circumference of a circle (C = 2Ï€r) to find the radius:
18.5 = 2Ï€r
r = 18.5 / (2Ï€)
r ≈ 2.9 cm
Now, we can use the formula for the volume of a cone, which is V = (1/3)Ï€r^2h, where r is the radius of the base and h is the height:
V = (1/3)Ï€(2.9)^2(12.2)
V ≈ 102.3 cm^3
Therefore, the volume of the right circular cone is approximately 102.3 cubic centimeters.
