Tolong y nmr 24 30 dan dibwhny itu + pke cara
makasih..

Answer 1

24. K = 4 × sisi
= 4 × 17 = 68 cm (c)
30. V1 = s³
= 16³ = 4.096 cm³
V2 = La × t
= (1/2 × a × t) × t
= (1/2 × 16 × 10) × 16
= 80 × 16 = 1.280 cm³
>> 4.096 + 1.280 = 5.376 cm³ (b)

K1 = 4 × sisi
= 4 × 14 = 56 cm
K2 = 2Πr
= 2 × 22/7 × 14
= 88 cm × 1/4 = 22 cm
>> 56 + 22 = 78 cm (a)

semoga membantu
