Question

(9) If the perimeter of circle is 44m then radius is...
(a) 7m
(b) 3.5m
(c) 22m
(d) 3m​

Answer 1

I THINKS 22 IS THE ANSWER

Answer 2

★ 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
