Answer:

Diameter = 103.35 cm

Explanation:

Pizza = circle

Area of a Circle = π * r²

π = 3.1416

r = radius

Area of a pizza = 850cm²

850 = 3.1416 * r²

850/3.1416 = r²

270.56 = r²

√270.56 = √r²

16.45 = r

radius = 16.45 (aprox)

diameter of a pizza = 2π r

diameter of a pizza = 2*3.1416*16.45

diameter of a pizza = 103.35 cm
