Question

If circumference of a circle is 44cm find its area

Answer 1

circumference=2πr
2×3.14×r=44
6.28×r=44
r=44/6.28
r=7
area=πr^
3.14×7×7
3.14×49
=153.86

Answer 2

${\huge{\underline{\rm{\pink{AnsWer : }}}}}$

✦ Circumstances of a circle is given by :

⇒ 2πr = 44

⇒ 2 × 22/7 × r = 44

⇒ r = 44*7/22*2

⇒ r = 44*7/44

⇒ r = 7cm.

✦ Area of the circle is given by :

→ πr²

→ 22/7 × (7)²

→ 22 × 7

→ 154cm² ans.

Therefore, the area of the circle is 154cm² ☑
