For radius = 1, let's play the game of 1/2 Phew AKA 90° arc segment AKA 1.58578. If the circle line has the ratio of 0.79289 of the diameter, so the value of that arc length equals 1.58578 : √0.79289 AKA 1.78089.

Proof: 1.78089 × 1.78089 equals 3.17157 which is the circle area.

Let's calculate (especially) the SPHERE AREA. (The sphere volume calculation will be straight 1.58578 as it is).

The former formula >> sA= (3.17157×6.34314)× 0.79289^2 = 12.6476 is not too accurate because there's two type of realities in spherical area to deal with, i.e.

1. Two poles (domes) with 1.58578 of diameters.

2. One curved Tape around equator with wide of 1.58578.

Let me introduce the concept of 0.890445517 which equals √0.79289

Curved Tape = wide × 0.890445517 x C = 1.58578 × 0.890445517 × 6.34314 = 8.9568.

The Polar Dome area = 1.58578^2 × 0.890445517^2 × √0.890445517 = 1.881515

Total Sphere Area = Curved Tape + 2 Polar Dome areas = 8.9568 + 2 [1.881515] = 12.71991

A little bit more than 4 Phew >> 4.01 times of Phew.

This is the clearest explanation ever.

Consider this is just a ~Cuick Count~. See you next in the ~Real Count~.
