carilah keliling lingkaran berikut : a. r: 6 cm b. r: 17 cm. c.d:32 cm. d. d : 45,5 cm
![]()
a. r = 6cm
K = 2πr
= 2 × 3,14 × 6
= 2 × 18,84
= 37,68cm
b. r = 17cm
K = 2πr
= 2 × 3,14 × 17
= 2 × 53,38
= 106,76cm
c. d = 32cm
r = ½d = 16cm
K = 2πr
= 2 × 3,14 × 16
= 2 × 50,24
= 100,48cm
d. d = 45,5cm
r = ½d = 22,75cm
K = 2πr
= 2 × 3,14 × 22,75
= 2 × 71,435
= 142,87cm
