Question

Tlng di isi ya dg caranya plessss.....

Answer 1

33) p = l = d.bola = 7 cm
t = 3.d bola = 3.7 = 21 cm
jadi,
Lp. balok = 2.(pl+pt+lt)
= 2.(7.7+7.21+7.21)
= 2.(49+147+147)
= 2.343
= 686 cm² ....(B)


34) B.

35) Lp.prisma = 2.L alas + K alas.t
= 2.p.l + 2.(p+l).t
= 2.12.8 + 2.(12+8).15
= 192 + 2.20.15
= 192 + 600
= 792 cm² ....(D)
