The volume of the layer between radius $r$ and radius $r+\delta r$ is (to a close approximation if $\delta r$ is small enough) the area $4\pi r^2$ times its thickness: $4\pi r^2\cdot\delta r$.
Web2 Answers. Sorted by: 3. The Wikipedia article gives the volume of the 4-dimensional hypersphere, with radius r, to be. V = π 2 2 r 4. The surface area can be found by differentiating with respect to r: A = d V d r = 2 π 2 r 3. The article also gives a proof of how to calculate the volume, and hence surface area. Share. WebSurface Area of Sphere Examples. Example 1: If the radius of a sphere is 20 feet, find its surface area. (Use π = 3.14). Solution: Given, the radius 'r' of the sphere = 20 feet. The surface area of the sphere = 4πr 2 = 4 × π × 20 2 = 5024 feet 2. ∴ The surface area of the sphere is 5024 feet 2.
WebSurface area of a sphere. The surface area formula for a sphere is 4 x π x (diameter / 2) 2, where (diameter / 2) is the radius of the sphere (d = 2 x r), so another way to write it is 4 x π x radius 2.Visual on the figure below: A sphere's surface area can be calculated just by knowing its diameter, or radius (diameter = 2 x radius). π is, of course, the well-known … WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given …
WebJun 6, 2011 · cube. Say they both have a volume of 1000cm3. First the cube Could measure 10cm by 10cm by 10cm So surface area = 6 x 100 = 600cm3 Now the sphere 1000cm3 = 4/3 π r3 r = 6.20350490899. Surface area = 4π r2 = 4 x π x 6.2030504908992 = 483.52673998cm3. So the cube has a higher surface area. Share.
