Question

Volume sebuah bola 113,04 liter. hitunglah panjang diameternya jika phi = 3,14

Answer 1

Vol bola = 4/3 .3.14 .r³
113.04 = 4/3 x 3.14 x r³
r³= 27
r=∛27
=3 cm

diameter = 2 x r
=6 

Answer 2

V = 4/3πr^3
113,04 dm^3 = 4/3 x 3,14 x r^3
113,04 dm^3 = 4,19r^3
r^3 = 113,04 dm^3/4,19
r^3 = 26,98 dm^3
r = √26,98 dm^3
r = 2,99 dm
d = 2r = 2 x 2,99 dm = 5,98 dm
