Jawaban:
1. a) L= 22/7. 7²
= 154cm²
K= 22/7. 14
= 44cm
b) L= 3,14 (10,5)²
= 346,185 cm²
K= 22/7.21
= 66cm
C) L= 3,14. 10²
= 314cm²
K= 3,14. 20
= 62,8cm
2. L= 3,14.44²
= 6.079,04cm²
3. L= 616cm²
616= 22/7. r²
196= r²
14. = r
K= 22/7. 28
= 88cm
4. K= 3,14.70
= 219,8cm = 2,198m
Jarak yg ditempuh 2,198m X 100 putaran = 219,8m
5. L taman= 22/7. 14.14
= 616m²
L kolam= 22/7. 1,75
= 5,5m²
L yg ditanami rumput 616m²-5,5m²= 610,5m²
Biaya yg harus dikeluarkan 610,5m² X 30.000 = Rp 18.315.000
