Diketahui luas permukaan bola adalah 616 cm2 . Hitunglah volume bola tersebut ?

[tex]Lp=616 \\ 4\pi r^2=616 \\ \pi r^2=154 \\ \frac{22}{7}r^2=154 \\ r^2=154\times\frac{7}{22} \\ r^2=49 \\ r=\sqrt{49} \\ r=7 \\ \\ \\ V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\times \frac{22}{7}\times 343 \\ V=\frac{4312}{3}$ cm^3$[/tex]

[tex]4 \pi r ^{2} = 616
 \pi r ^{2} = 154
 \frac{22}{7}r^{2} = 154
r ^{2}=49
r= \sqrt{49}
r= 7 [/tex]

pakai rumus
[tex] \frac{4}{3} \pi r^{3} = \frac{4}{3} \frac{22}{7} 7^{3} = \frac{4312}{3} [/tex]
