(ii) diameter -49m
(iii) diameter-9.8m
(iv) radius -5 cm

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Solutions :-

Given :
i) Radius = r = 14 m

Area of circle = πr² sq. units
= 22/7 × 14 × 14 m²
= 22 × 2 × 14 m²
= 616 m²

ii) Diameter = 49 m
Radius = r = 49/2 = 24.5 m

Area of circle = πr² sq. units
= 22/7 × 24.5 × 24.5 m²
= 1886.5 m²

iii) Diameter = 9.8 m
Radius = r = 9.8/2 = 4.9 m

Area of circle = πr² sq. units
= 22/7 × 4.9 × 4.9 m²
= 75.46 m²

iv) Radius = r = 5 cm

Area of circle = πr² sq. units
= 22/7 × 5 × 5 m²
= 78.57 m² (approx.)
