Solution :
To find the area first we need to find the radius of the circle from the diameter.
Diameter = 28 cm
Radius = diameter/2
= 28/2
= 14 cm
Area of circle = Π r ²
= (22/7) ⋅ (14)²
= (22/7) ⋅ 14 ⋅ 14
= 22 ⋅ 2 ⋅ 14
= 44 ⋅ 14
= 616 cm²

Answer:
Diameter = 1.4 m
Radius = diameter/2
= 1.4/2
= 7 m
Area of a circle = pir²
= (22/7)×7×7
= 1.54 cm²
