Question

the circumference of a circle is 35.2 M find its area

Answer 1

Circumference = 35.2 m

2*pi *r = 35.2

=> 2*22*r/ 7 = 35.2

=> r = 35.2 * 7 / 44

=> r = 0.8 * 7

=> Radius of circle = 5.6 m


Area = pi *r^2

= 22 * 5.6 * 5.6 /7

= 22* 0.8 * 5.6

= 98.56 m^2

Answer 2

heya frnd!

here's ur answer...

given the circumference of the circle is 35.2m.

therefore 2πr=35.2m

→2×22/7×r=35.2m

→44/7×r=35.2m

→r=35.2/1×7/44

→r=246.4/44

→r=5.6m

★verification★

circumference of circle=2πr

=2×22/7×5.6

=44/7×5.6

=246.4/7

=35.2m²

hence verified

thus the radius of the circle is 5.6m

area of the circle=πr²

=22/7×5.6×5.6

=689.92/7

=98.56m²

hope this helps..!
