bisa minta tolong bantu jawab no:26 dan 27

nomor 26
EF = (AE x BC)+(BE x AD)/AE+BE
20 = (5 x 23) + (BE x 15)/5+BE
20 = 115 + 15BE/5+BE
20(5+BE) = 115+15BE
100+20BE = 115+15BE
20BE-15BE = 115-100
5BE = 15
BE = 15/5
BE = 3
Panjang AB = AE+BE
= 5+3 = 8 cm (C)

nomor 27
V tabung = π r r t
= 22/7 x 7 x 7 x 15
= 22 x 7 x 15
= 2310 cm^3 (D)

*semoga membantu. sukses selalu ^_^
