Answer:

Diameter = 14 cm

Radius(r) = Diameter/2

=> 14/2 = 7cm

Circumference of circle

=> 2 π r

=> 2 × \frac{22}{7}

7

22

× 7

=> 2 × 22

=> 44 cm

Therefore, circumference of circle= 44 cm.

___________________

Area of circle = π r ²

=> \frac{22}{7}

7

22

× 7 × 7

=> 22 × 7

=> 154 cm²

Therefore, Area of circle = 154 cm²
