Kulę o promieniu 2m przetopiono na kulki o promieniu 2,5cm Ile jest kulek o promieniu 2,5cm? PROSZĘ O POMOC:D
Dane:
Duża kula :
R = 2m
V= 4/3 πR³
V = 4/3 * 2³ *π
V = 4/3 * 8 π = 32/3 π m³
Mała kula:
r= 2,5 cm = 0,025 m
V₁ = 4/3 * (0,025)³π = 4/3 * 0,000015625 π =0,0000625/3 π m³
V:V₁ = 32/3 π : 0,0000625π/3 = 32π/3 * 3/0,0000625π = 32: 625/10000000=
= 32 * 10000000/625 = 320000000/625 = 512 000 szt
