Circumference = 2πr = 2 * 22/7 * r
2 * 22/7 * r = 44 cm
r = 44 * 7 / 2 * 22 = 44 * 7 / 44 = 7 cm
Therefore area = πr² = 22/7 * 7²
=22/7 * 49 = 22 * 7 = 154 cm²
Therefore are = 154 cm²
Hope this helps!!

Hi there!
Given,
Circumference = 44 cm
2πr = 44
2 × 22/7 × r = 44
r = 44 × 7/ 2 × 22
r = 7 cm
[ Radius, r = 7cm ]
Area of the Circle = πr²
= 22/7 × 7 × 7
= 22 × 7
= 154 cm²
Hence,
Area of the circle is = 154 cm²
