Question

Tolong bantu jawab plisss pakek caranya nomor 3

Answer 1

(2).
Volume = debit × waktu
Volume = 550.000 × 10
Volume = 5.500.000 liter
(3).
a² = s² - t²
a² = 18² - 14²
a² = 324 - 196
a² = 128
a = √128
a = 8√2 cm
Luas total = Luas jajar genjang + Luas ½ lingkaran
Luas total = (a × t) + (phi × r² : 2)
Luas total = (8√2 × 14) + (3,14 × 9² : 2)
Luas total =
42117
——— + 112√2 = 579,56 cm²
