Question

Ada yg tau nmr 20 gak

Answer 1

Panjang busur AB / pnjang busur CD = < AOB / < COD
88 / panjang busur CD = 120 / 30
panjang busur CD = 88 / 4
panjang busur CD = 22 cm

semoga membantu ya :)

Answer 2

<AOB = 120
<COD = 30

busur AB = 88
Maka
AB = 120/360 x π x d
AB = 120/360 x K
88 = 1/3 x K
88 x 3 = K
264 = K

maka
CD = 30/360 x K
CD = 1/12 X 264
CD = 22

jadi yg A
