Answer 1

Penjelasan dengan langkah-langkah:

BANGUN RUANG LENGKUNG

• T A B U N G

d = t = 100 cm

d = t = 10 dm

r = 5 dm

π = 3,14

Harga = Rp. 13.000/liter

Volume minyak tanah dalam drum

= πr²t

= 3,14 × 5² × 10

= 31,4 × 25

= 785 liter

Uang yang didapat Bu Maimunah

= Volume × harga per liter

= 785 × 13.000

= Rp. 10.205.000,00

naik bagi 10

turun kali 10

100 cm = ... dm

100 ÷ 10 = 10 dm

1 m = ... dm

1 × 10 = 10 dm

diameter = 10 dm

D = 2R

R = D ÷ 2

R = 10 ÷ 2

R = 5

V = π × r × r × t

V = 3,14 × 5 × 5 × 10

V = 15,7 × 5 × 10

V = 78,5 × 10

V = 785 dm³ = 785 liter

785 × 13

= RP 10.205
