Question
A cone with height 6 cm and radius 2 cm has a hemispherical hole with radius 1 cm bored into the center of its base. Find the surface area and volume of this compound shape.
The image depicts a geometric figure of a cone with a hemisphere placed inside it near the top. The cone's wide base is horizontal, and its pointed tip extends downward, creating an inverted triangular shape. The hemisphere, shown in blue, fits snugly within the upper part of the cone, with its flat circular face aligned with the cone’s top opening. The hemisphere appears to occupy a portion of the cone's interior, demonstrating a spatial relationship between the two shapes. This diagram is useful for understanding the intersection of three-dimensional figures and could be applied in teaching concepts of volume and geometry.
