More About the calculation of volume and surface area of a Sphere

Use this calculator volume of a sphere calculator with steps. A little bit of background for you to understand the results better. In order to compute the area and the volume of a sphere of radius $r$ we use the following formulas:

$$\text{Area} = 4\pi r^2$$ $$\text{Volume} = \frac{4}{3}\pi r^3$$

Computationally speaking, it is really simple to compute the area and the volume of a sphere, by simply plugging the radius $r$ in the above formulas. For example, if the radius is $r = 3$, then we compute

$$\text{Area} = 4\pi r^2 = 4\pi \cdot 3^2 = 36 \pi$$ $$\text{Volume} = \frac{4}{3}\pi r^3 = \frac{4}{3}\pi \cdot 3^3 = \frac{108}{3} \pi = 36 \pi$$

which completes the calculation.
