Solution
Given :-
- Radius of circle = 5 m
Find :-
- circumference and its area
Explanation
Using Formula
★ Circumference of circle = 2πr
★ Area of circle = πr²
First calculate circumference
==> Circumference of circle = 2 × 22/7 × 5
==> circumference of circle = 220/7
==> circumference of circle = 31.42 m
And, now Calculate its Area
==> Area of circle = πr²
==> Area of circle = 22/7 × 5²
==> Area of circle = 22/7 × 25
==> Area of circle = 550/7
==> Area of circle = 71.4 m²
Hence
- Circumference of circle will be = 31.42 m
- Area of circle will be = 71.4 m²
