Dik: R=21 cm

Jawaban:

$color{aqua} underbrace color{orange} tt huge TABUNG$

$bold color{chocolate}RUMUS :$

1. Volume (V)

$tt V = pi.{r}^{2}. t$

2. Luas permukaan (L)

$tt L = 2.pi. r(r + t)$

$bold color{green}DIKETAHUI :$

$tt jari - jari(r) = 21 : cm$

$tt tinggi(t) = 10,5 : cm$

$bold color{violet}DITANYA :$

$tt Volume(V) = : ?$

$bold color{red}JAWABAN :$

$tt V = pi.{r}^{2}. t$

$tt V = frac{22}{7} times {21}^{2} times 10,5$

$tt V = frac{22}{7} times (21 times 21) times 10,5$

$tt V = frac{22}{ cancel7} times cancel{441} : {}^{63} times 10,5$

$tt V = 22 times 63 times 10,5$

$tt V = 1.386 times 10,5$

$tt V = underline{14.553 : {cm}^{3} }$

$bold color{pink}KESIMPULAN:$

$tt jadi, : volume : tabung : tersebut : adalah \ underline{ bold{14.553 : {cm}^{3}}}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~$
