Why Is The Volume Of A Sphere 4 3 Pi R Cubed

;The total of the triangle base edge lengths is $b=2\pi r$ and since the height is $h=r$ the total area is $\frac12hb=\pi r^2.$ If you show that the sphere has area $A=4\pi r^2$ then a three dimensional visualization with pyramids of height $h=r$ and bases on the sphere gives you a volume of $\frac13hA=\frac43\pi r^3.$ 2 Answers Sorted by: 3 One argument is that the surface area should be the derivative of the volume. Since the volume is proportional to the radius cubed ( V = aR3 V = a R 3 for some a a ), taking the derivative loses a power of R R and gains a factor of 3. A similar argument can be made with the polyhedra hint.

Why Is The Volume Of A Sphere 4 3 Pi R Cubed;Remember that when we say that the volume element is: dV = 4πr2dr (1) (1) d V = 4 π r 2 d r. We are talking about the limit in which dr → 0 d r → 0. If dr d r is extremely small then dr2 d r 2 is extremely extremely small and dr3 d r 3 is extremely extremely extremely small. So in the limit of dr → 0 d r → 0 we can simply ignore the ... Basically cut it up into thin wedges where the circumference is 2 pi r then it can be re arranged into length of thin wedges triangles of height r and area r 2 baselength The sum of them must be r 2 2 pi r as their bases correspond to the circumference

V = 4 3 π r 3 = 4 3 × 3.14 × 12 × 12 × 12 = 7234.56 cubic units. 2. Find the volume of the sphere whose diameter is 28 cm. Solution: Given, diameter = 28 c m. So, radius = D i a m e t e r 2 = 28 2 = 14 c m. From there, we can use the formula, which is. V = 4 3 π r 3 = 4 3 × 3.14 × 14 × 14 × 14 = 11488.23 c m 3. 3.
