= 3,14 × 4

= 12,56

B. 3,5 cm

K = π × d

= 22/7 × 3,5

= 11

C. 7 cm

K = π × d

= 22/7 × 7

= 22

D. 10 cm

K = π × d

= 3,14 × 10

= 31,4

E. 35 cm

K = π × d

= 22/7 × 35

= 110

2)

A. 2,5 cm

K = 2 × π × r

= 2 × 3,14 × 2,5

= 15,7

B. 10 cm

K = 2 × π × r

= 2 × 3,14 × 10

= 62,8

C. 28 cm

K = 2 × π × r

= 2 × 22/7 × 28

= 176

D. 56 cm

K = 2 × π × r

= 2 × 22/7 × 56

= 352

mangap kalo kurang tepat, moga membantu
