Question

Oblicz promień kuli o podanej objętości:
a) 288 pi cm3
b) 4 1/2pi cm3
c) 188 2/3pi cm3

Answer 1

4/3pir3=288pi cm3 /4/3pi
r^3=216 cm3
r=6 cm

4/3pir3=4 1/2pi cm3 /4/3pi
r^3=3.375
r=1.5 cm

4/3pir3=188 2/3pi cm3 /4/3pi
r^3=141.5
r=5.21 cm

Answer 2

A) v=4/3pi r^3   4/3 pi r^3=288 pi      4/3r^3=288     r^3= 216     r=6
b) 4/3pir^3= 4 1/2 pi         4/3r^3=4 1/2   r^3=3,375 r=1,5
c) 4/3pir^3=188 2/3pi         4/3r^3=188 2/3  r^3=141,5
