Answer:
Correct option: Second one -> 141.3 cm3
Step-by-step explanation:
The volume of "snow" is the sum of the half sphere volume and the cone volume.
The volume of the half-sphere is given by the formula:
V = (2/3) * pi * radius^3
If the half sphere has a radius of 3 cm, we have that:
V1 = (2/3) * pi * 3^3 = 56.5 cm3
The volume of the cone is given by:
V = (1/3) * pi * radius^2 * height
If the radius is 3 cm and the height is 9 cm, we have:
V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3
So the final volume is:
V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3
Correct option: Second one
