Answer 2

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 )
