Question

Ada yg tau jawaban no 1,2,3,4,5

Answer 1

1))
L slimut tabung = πrt
616 = πr14
22/7. r = 44
r = 14


Lp = 2πr² + L slimut
Lp = 2.22/7.14.14 + 616
Lp = 1848

2))
L = πrt = 22/7.0,7.5 = 11m²

3))
Lp = 2πr(r+t)
Lp = 2.22/7.14(14+20)
Lp = 88.34
Lp= 2992 cm²

4))
L = L balok tanpa tutup + L1/2 tabung
L = (pl + pt + 2lt) + (πr² + 1/2πrt)
L = (4.5 + 2.5.2 + 2.4.2) + (3,14.2.2 + 1/2.3,14.2.5)
L = (20+20+16) + (12,56+15,7)
L= 56 + 28,26 = 84,26

5))
L = πr² + 2πrt
L = 22/7.49.49 + 2.22/7.49.150
L = 7546 + 46200
L = 53746 cm²
