★ Given :-
- Perimeter of circle = 44 m
★ Have to Find :-
- What's the radius of circle.
★ Solution :-
As we know that the circumference of circle is equal to the perimeter .
So,
Circumference of circle → 2πr
Substituting the given values.
⇒ 2 × 22/7 × r → 44
⇒ 44 × r → 44 × 7
⇒ r = 44 × 7/44
44 cancels 44
r = 7 m
Hence, The radius of circle is 7 m
