7. Kll lingkaran = 2πr 37,68 = 2×22/7×r r = 37,68 ×7/44 r = 12 cm (a) 8. KLL = 2πr = 2×3,14×15 = 157 cm jarak tempuh = 157 m = 15700 cm/ 157 = 100 kali (b) 11. aku kurang tau

11. 3.14x15x15:2 = 353,25 15x20 = 300 353,25+300= 653,25 jadi a jawabannya
37,68 = 2×22/7×r
r = 37,68 ×7/44
r = 12 cm (a)
8. KLL = 2πr
= 2×3,14×15
= 157 cm
jarak tempuh = 157 m = 15700 cm/ 157 = 100 kali (b)
11. aku kurang tau
15x20 = 300
353,25+300= 653,25
jadi a jawabannya
