Circumference= 154 × 22/7= 484 units
C= 2 × 22/7 × r
484 ×7/44 = r
77 units= radius
Area = 22/7 × r^2
A= 22/7 × 77unit × 77 units
A= 18634 unit^2
C= 2 × 22/7 × r
484 ×7/44 = r
77 units= radius
Area = 22/7 × r^2
A= 22/7 × 77unit × 77 units
A= 18634 unit^2

☆ GIVEN ☆
Circumference of circle = 154 pi
☆ TO FIND ☆
area of circle
☆SOLUTION ☆
As we know that
circumference of circle= 2×pi×r
154pi=2×pie×r
r=77 units
area of circle = pi × r^2
=22/7×77×77
=22×11×77
=1331×2×7
=1331×14
=18634 unit^2
so area of circle is 18634 units ^2
