<<ANSWER>>
Area of a sector = x/360×πr^2
Radius =56/2=28
= 45/360×22/7×28×28
=1/8×22/7×28×28
=22×3.5×28/7
=2156/7
=308

Answer:
Step-by-step explanation:
the diameter of circle = 56cm
So radius = 56/2= 28cm
aNd central angle =45
Since the area of a sector of a circle = theta / 360 (py r2)
= 45 /360(22/7 . 28.28)
308cm2
