Yang tahuu,, tolong di jawab yaa :) terima kasih sebelumnya...

33) s = 13 cm d₁ = 10 cm t = 15 cm (1/2d₂)² = 13² - 5² (1/2d₂)² = 169 - 25 (1/2d₂)² = 144 1/2d₂ = 12 d₂ = 24 cm luas alas = luas belah ketupat = 1/2 x d₁ x d₂ = 1/2 x 10 x 24 = 120 cm² volume limas = 1/3 x luas alas x tnggi = 1/3 x 120 x 15 = 600 cm³ (A)
34) d₁ = 16 cm d₂ = 12 cm sisi² = 8² + 6² sisi² = 64 + 36 sisi² = 100 sisi = 10 cm luas alas = 1/2 x d₁ x d₂ = 1/2 x 16 x 12 = 96 cm² luas prisma = ( 2 x luas alas ) + (keliling alas x tinggi) = ( 2 x 96 ) + ( (4 x 10) x 20 ) = 192 + 800 = 992 cm² (B)
d₁ = 10 cm
t = 15 cm
(1/2d₂)² = 13² - 5²
(1/2d₂)² = 169 - 25
(1/2d₂)² = 144
1/2d₂ = 12
d₂ = 24 cm
luas alas = luas belah ketupat
= 1/2 x d₁ x d₂
= 1/2 x 10 x 24
= 120 cm²
volume limas = 1/3 x luas alas x tnggi
= 1/3 x 120 x 15
= 600 cm³ (A)
34) d₁ = 16 cm
d₂ = 12 cm
sisi² = 8² + 6²
sisi² = 64 + 36
sisi² = 100
sisi = 10 cm
luas alas = 1/2 x d₁ x d₂
= 1/2 x 16 x 12
= 96 cm²
luas prisma = ( 2 x luas alas ) + (keliling alas x tinggi)
= ( 2 x 96 ) + ( (4 x 10) x 20 )
= 192 + 800
= 992 cm² (B)
Semoga membantu ya :)
