Find the area of the following circles, given that :
(a) Radius = 14 mm
(b) Diameter = 49 m
(c) Radius = 5 cm
(a) It is given in the question that,
Radius of the circle = 14 mm
We know that,
Area of the circle = πr2
∴ Area = 
× 14 × 14
= 22 × 2 × 14
= 616 mm2
(b) It is given in the question that,
Diameter of the circle = 49 m
Radius of the circle = 
m
We know that,
Area of the circle = πr2
∴ Area = 
= 11 × 7 × 49/2
= 1886.5 m2
(c) It is given in the question that,
Radius of the circle = 5 cm
We know that,
Area of the circle = πr2
∴ Area = 
= 78.57 cm2
