Question

Luas permukaan bola yang voumenya 113.040 cm³ dan π = 3,14 adalha

Answer 1

V = 4/3 pi r^3
113040 = 4/3 3,14 r^3
3,14 r^3 = 113040 x 3/4
3,14 r^3 = 84780
r^3 = 27000
r = 30 cm

Answer 2

V=4/3*Phi*r^3
113040=12,56/3*r^3
113040*3/12,56=r^3
339120/12,56=r^3
27000=r^3
30=r
Lp=> 4*phi*r^2
4*3,14*30*30
11304
