10. Berapakah volume bangun ruang bola
tersebut?
«Penyelesaian Soal »
9. Luas permukaan Bola
Lp bola = 4 × Ο × r × r
[tex]lp = 4 \times \pi \times r \times r[/tex]
[tex]lp = 4 \times \frac{22}{7} \times 7 \: cm \times 7 \: cm[/tex]
[tex]lp = \frac{4 \times 22 \times 7 \times 7}{7} [/tex]
[tex]lp = \frac{4.312 \: cm}{7} [/tex]
[tex]lp \: bola = 616 \: {cm}^{3} [/tex]
10. Volume Bola
Volume Bola= ⁴/3 × Ο × r × r × r
[tex]v \: = \frac{4}{3} \times \pi \times r \times r \times r[/tex]
[tex]v = \frac{4}{3} \times \frac{22}{7} \times 7 \: cm \times 7 \: cm \times 7cm[/tex]
[tex]v = \frac{4}{3} \times \frac{22 \times 7 \times 7 \times 7}{7} [/tex]
[tex]v = \frac{4}{3} \times \frac{7.546}{7} [/tex]
[tex]v = \frac{4}{3} \times 1.078 \: cm[/tex]
[tex]v = \frac{1.078 \: cm \times 4}{3} [/tex]
[tex]v = \frac{4.312 \: cm}{3} [/tex]
[tex]v = 1.437.33 \: {cm}^{3} [/tex]
