Sebuah lingkaran berdiameter 16 cm
r = d÷2
r= 16 ÷ 2
r= 8 cm
K= 2 × π × r
K= 2 × 3.14. × 8 cm
K= 6.28 cm × 8 cm
K= 50.24 cm
L= π × r × r
L= 3.14 × 8 cm × 8 cm
L= 25.12 cm × 8 cm
L= 200.96 cm²
Semoga Bisa Bermanfaat..

d = 16 cm
K = πd
K = 3,14 × 16
K = 50,24 cm
L = ¼πd²
L = ¼ × 3,14 × 16 × 16
L = 0,25 × 803,84
L = 200,96 cm²
