Question

volume gabungan gambar diatas adalah...... cm³​

Answer 1

Diketahui:

• r = d : 2 = 14:2 = 7cm
• t = 10cm

Ditanya: Volume gabungan?

Jawab:

Vgabungan = Vbola + Vtabung

Vgabungan = [tex](4\pi r^3) + (\pi r^2t)[/tex]

Vgabungan = [tex](4\times\frac{22}{7}\times7\times7\times7) + (\frac{22}{7} \times7\times7\times10)[/tex]

Vgabungan = [tex](88\times49cm^2)+(22\times70cm^2)[/tex]

Vgabungan = 4.312cm^3 + 1540cm^3

Vgabungan = 5.852cm^3
