Answer: (3) 154 cm²

Explanation:-
Formula –
The circumference of a circle = 2 π r

Then, the 2 x 22 x r/7 = 44
r = 7

Formula –
The area of the circle = π r²

Then, the area of the circle = 22 x 7 x 7 /2
= 22 x 7
= 154 cm²

Then, the area of the  circle is 154 cm².

Hence, the answer is (3) 154 cm².
