tolong jawab pake cara ya no.25

25 ) Keliling = 1/2 × π × d + 30 + 14 + 30
= 1/2 × 22/7 × 14 + 74
= 22 cm + 74 cm
= 96 cm (C)

14+30+30=74

rumus keliling lingkaran = phi x D
D = 14
Phi = 22/7
22/7 x 14 = 44
44 ÷ 2 = 22

Keliling persegi panjang + keliling setengah lingkaran
= 74 + 22 = 96

C. 96 cm

Maaf kalo salah, semoga membantu :)
