Answer 1

1) C

2) B

3) B

4) C

5) Vbalok = p x l x t = 27 x 24 x 9 = 5832

vbalok = vkubus

maka vkubus = s³

5832 = s³

s =³√5832 = 18 cm (c)

6) k = 2πr

62,8 = 2 x 3,14 x r

62,8 = 62,8r

r = 62,8/62,8 = 10 cm

jadi v = ½ x la x t = ⅓ x 3,14 x 10 x 10 x 21 = 2198 cm³ (b)

7) Volume prisma = La x t = 104 x 25 = 2600 cm³

8) v = s³ = 7³ = 343 satuan

9) v = La x t

= 22/7 x 14 x 14 x 11

= 6776 cm³

10) v = p x l x t = 16 x 18 x 10 = 2880 cm³

11) v = ⅓ x la x t

= ⅓ x 22/7 x 21 x 21 x 30

= 13860 cm³
