    Answer:

    Curved Surface Area: The area of the outer surface of the hemisphere is called the curved surface area. From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units.

    Total surface area:Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

    Volume of sphere:The formula for the volume of a sphere is V = 4/3 πr³. See the formula used in an example where we are given the diameter of the sphere.

    Answer:

    Formula of hemisphere:

    V(sphere) = 4/3 * π * r³ . Therefore, the volume of a hemisphere formula is as follows: V = V(sphere)/2 , V = 2/3 * π * r³ .

    Formula of curved surface area of Hemisphere:

    From the surface area of a sphere, we can easily calculate the surface area of the hemisphere. The curved surface area of a hemisphere = 2πr2 square units. We know that the base of the hemisphere is circular in shape, use the area of the circle.

    Formula of total surface of hemisphere:-

    The total surface area of a hemisphere = 3πr2 square units

    The total surface area of a hemisphere = 3πr2 square units“r” is the radius of the hemisphere.

    Formula of volume of sphere:

    V=4/³

    r=Radius
