Answer 1

Rumus keliling lingkaran = 2 x π x r 
r. luas lingkaran = π x r x r 

2. keliling = 2 x 3,14 x 35 = 219,8cm
luas = 3,14 x 35 x 35 = 3846,5cm²

3. keliling = 2 x 3,14 x 56 = 351,68cm
luas = 3,14 x 56 x 56 = 9847,04cm²

5. keliling = 2 x  x 40 = 10.048cm
luas = 3,14 x 40 x 40 = 5024cm²

8. r = 100/2 = 50
keliling  = 2 x 3,14 x 50 = 314cm
luas = 3,14 x 50 x 50 = 7850cm²
