Answer:
Step-by-step explanation:
a) ∠AOB = 45°
b) ∠BDC = 45°
c) ∠BFC = 67 1/2
d) ∠FBC = 67 1/2
e) Given,
Radius of pizza = 10.5 cm
Area of each piece of pizza = πr^2 = 3.14 × 10.5 × 10.5 (π value = 22/7 or 3.14)
= 314 /100 × 105/10 × 105/10
= 314 × 105 × 105 / 10000
= 3461850 / 10000
= 346.185 = 346.5cm^2 (nearly )
