Circumference of the circle = 264 cm
2πr = 264
2 × ( 22/7 ) × r = 264
r = ( 264 × 7 ) / ( 2 × 22 )
= (11 × 2 × 7 × 7 ) / ( 2 × 2 × 11 )
= 49/2
=29.5
A = ( 22/7 ) ( 49/2 ) ( 49 /2 )
= 3773/2
= 1886.50 cm²

Circumference of a circle=264
2πr=264
2×22/7×r=264
r=264×7/2×22
r=6×7=42cm
Therefore, area of a circle=πr square
= 22/7×42×42
=22×6×42
=132×42
=5544cm square.
