Oblicz objętość kuli której pole powiechrzni wynosi
36
___
25 Pi cm 2
Pp= 4πr²
(36/25) * π= 4π r² /:4π
(36π/25) * (1/4π)= 4π r²/4π
9/25=r²
r=√(9/25)
r=3/5
r=0,6
V=(4/3) * πr³
V=(4/3) * π * 0,6³=0,288*π=0,288*3,14≈0,9cm³
p=4πr²=36/25π /:4π
r²=0,36
r=√0,36
r=0,6cm=promień kuli
v=4/3πr³=4/3π×0,6³=0,288πcm³
