R - promień
P - pole
V - objętość
Wzór na pole kuli
P = 4πR²
Wzór na objętość kuli
V = 4/3πR³
R = 3
V = 4/3*π*3³ = 4/3π*27 = 36π
R = ?
V = ?
P = 256 π
4πR² = 256π |:4π
R² = 64
R = 8
V = 4/3π*8³ = 4/3π*512 = 2048/3π = 682 ²/₃ π
R =?
P = ?
V = 32/3π
4/3πR³ = 32/3π |:π
4/3R³ = 32/3 |*3/4
R³ = 8
R = ∛8 = 2
P = 4*π*2² = 4π*4 = 16π
R = ?
V = ?
P = 3,24π
4πR² = 3,24π |:4π
R² = 0,81
R = 0,9
V = 4/3π*(0,9)³ = 4/3π*0,729 = 0,972π
