d³=6V÷π
d³=6. 113040 ÷ 3,14
d³=216000
d=√216000=60 cm
Luas bola
=πd²
=3,14 . 60²
=11304 cm²
pertama cari R
V bola = 4/3 x phi x r3
113.040 = 4/3 x 3,14 x r3
3,14r3 = 113040 x 3/4 = 84780
r3 = 84780 : 3,14
R3 = 27000
R = 30 cm
L bola = 4 phi r2
4x 3,14 x 30 x 30
12,56 x 900
= 11304 cm 2
lumayan rumit :v
