Q. [ 7/10 ]

r = 28 cm ÷ 2 = 14 cm

  • Volume

tt =pi {r}^{2} t

tt = frac{22}{7} times {14}^{2} times 32

tt = frac{22}{7} times 196 times 32

tt = frac{137.984}{7}

= 19.712 cm³

purple{boxed{blue{boxed{green{star{orange{ : : mathcal{JK} : : : {green{star}}}}}}}}}

<<< MATH ERPRAMZ >>>

DIKETAHUI :

  1. TINGGI = 32 CM
  2. JARI – JARI = 28 CM ÷ 2 = 14 CM ( DIAMETER )

TENTUKAN :

V !

JAWAB :

V = π × R × R × T

= 22/7 × 14 CM × 14 CM × 32 CM

= 22 × 2 × 14 CM × 14 CM × 32 CM

= 44 CM × 14 CM × 32 CM

= 616 CM × 32 CM

= 19.712 CM³
