Diagram 2 shows sector OPQ with centre O and sector PXY with centre P .
Diberi bahawa OQ = 20 cm, PY = 8cm, ∠ XPY = 1.1 radian
dan panjang lengkok PQ =14 cm. Hitung
Given that OQ = 20 cm , PY = 8 cm , ∠ XPY = 1.1 radians
and the length of arc
PQ = 14 cm. Calculate
(a) nilai θ dalam radian,
the value of θ, in radian
