Question

The circumference of a circle is 704 cm,find its area

Answer 1

The circumferince of the circle is 2πR ;
The area of the circle is π$R^{2}$;
Then, 2πR = 704 ;
R = 352 / π ;
π$R^{2}$ = π × ( 352 / π )^2 = ( 352^2) / π = 123904 / π ≈ 39459.87 ≈ 39460 cm^2 ;

Answer 2

If the circumference of a circle is 704 cm, then the area is: 39439.87 cm.

The formula looks like this:  A = π r 2 and C = 2 π r.

So, C = 704 cm and A = 39439.87 cm.

Hope I helped!
