Question

Tentukan volume bola yang memiliki:
a.r=5cm
b.r=4,2
c.d=12
d.r=21
beserta caranya

Answer 1

A) r = 5cm
v = 4/3 . pi . r^3
v = 4/3 . 3,14 . 125
= 523,3cm^3
b) r = 4,2 dm
v = 4/3 . pi . r^3
v = 4/3 . 3,14 . 74,088
= 310,18176dm^3
c) d = 12cm r = 6cm
v = 4/3 . pi . r^3
= 4/3 . 3,14 . 216
= 904,32cm^3
d) r = 21cm
v = 4/3 . pi . r^3
= 4/3 . 3,14 . 21^3
= 38772,72cm^3
