23 cze 2024 · When we split a sphere in half and take one of the resulting parts, we get a hemisphere. In each hemisphere, we can name two surface areas: base and cap areas (see the picture above). From the area of a sphere calculator, we know that the surface area of a sphere is as below: A(sphere) = 4 × π × r²

4 dni temu · Now we can try to derive various surface areas of sphere formulas. In this area of a sphere calculator, we use four equations: Given radius: A = 4 × π × r²; Given diameter: A = π × d²; Given volume: A = ³√(36 × π × V²); and; Given surface to volume ratio: A = 36 × π / (A/V)².
Curved Surface Area of a Hemisphere Formula. The curved surface area of a hemisphere is the area covered by its curved surface. It is exactly half of the surface area of a sphere. The curved surface area of a hemisphere with radius 'r' can be calculated using the following formula.
Surface area of half a sphere = Curved Surface Area of a Hemisphere. So, we simply need to divide the total surface area of the sphere by 2 to get the curved surface area of the hemisphere. Curved Surface Area of Hemisphere Formula = 2πr2. where ‘r’ is the radius of the hemisphere.
A hemisphere, for those scratching their heads, is simply half a sphere. Therefore, the formulas to calculate its volume and surface area are straightforward. Here they are, presented in a code-like format for your convenience: Volume = 2/3 * π * radius^3. Surface Area = 3 * π * radius^2.
The total surface area of the sphere = Curved surface area of sphere + base area. We know that the base of the hemisphere is circular in shape, use the area of the circle. TSA = 2πr 2 + πr 2 = 3πr 2. Therefore, The total surface area of a hemisphere = 3πr2 square units. Where π is a constant whose value is equal to 3.14 approximately.
