Jawaban:
[tex]s = \sqrt{ {r}^{2} + {t}^{2} } \\ = \sqrt{ {7}^{2} + {24}^{2} } \\ = \sqrt{49 + 576 } \\ = \sqrt{625} \\ = 25 \: cm \\ \\ Lp.gab = Lp.kerucut + Lp.tabung \\ = (Ο \times r \times (r + s)) + (2 \times Ο \times r \times (r + t)) \\ = ( \frac{22}{7} \times 7 \times (7 + 25)) + (2 \times \frac{22}{7} \times 7 \times (7 + 10)) \\ = (22 \times 32) + (44 \times 17) \\ = 704 + 748 \\ = 1.452 \: {cm}^{2} [/tex]
