Verified answer

Jawaban:

[tex] \boxed{\sf{L.Permukaan_{Kerucut} = \red{ {3.696 \: cm}^{2} }}} \\ [/tex]

[tex] \boxed{\sf{Volume_{Kerucut} = \red{ {3.234 \: cm}^{3} }}} \\ [/tex]

Penjelasan dengan langkah-langkah:

[tex] \bf \blue{L.Permukaan_{Kerucut}} \\ [/tex]

[tex] \sf{L.Permukaan_{Kerucut} = \pi \times r \times (r + s)} \\ [/tex]

[tex] \sf{ = \frac{22}{\cancel{7}} \times \cancel{21} \times (21 + 35)} \\ [/tex]

[tex] \sf{ = 22 \times 3 \times (21 + 35)} \\ [/tex]

[tex] \sf{ = 66 \times 56} \\ [/tex]

[tex] \sf{ = \underline{\red{ {3.696 \: cm}^{2} }}} \\ [/tex]

=======================

[tex] \bf \blue{Volume_{Kerucut}} \\ [/tex]

[tex] \sf{Volume_{Kerucut} = \frac{1}{3} \times \pi \times {r}^{2} \times t} \\ [/tex]

[tex] \sf{ = \frac{1}{\cancel{3}} \times \frac{22}{\cancel{7}} \times \cancel{21} \times \cancel{21} \times 7} \\ [/tex]

[tex] \sf{ = 1 \times 22 \times 7 \times 3 \times 7} \\ [/tex]

[tex] \sf{ = \underline{\red{ {3.234 \: cm}^{3} }}} \\ [/tex]
