Question

K = 132 cm
tentukan panjang diameter dan jari² lingkaran diatas tersebut!!
Jangan lupa pakai caranya!!​

Answer 1

Verified answer

K = π × d/2 × π × r

132 = 3,14 × d

d = 132 ÷ 3,14

d = 42,03 (dibulatkan)

d = 42 cm

r = (42 ÷ 2) cm

r = 21 cm

Answer 2

Penjelasan dengan langkah-langkah:

☁Penyelesaian ☁

[tex] \boxed{ \sf kel = \pi \times d \: }[/tex]

132 = 22/7 × d

132 = 132 × 7/22

132 = 924/22

d = 42cm
