Question

If the circumference of a circle is 121cm.find its area

Answer 1

r = 77/4
area = 22/7 × 77/4 × 77/4
= 714.125 ANSWER
thanks...

Answer 2

hiii!!!

here's ur answer...

circumference of the circle = 121cm

therefore 2πr = 121cm

=> 2×22/7×r = 121cm

=> 44/7×r = 121cm

=> r = 121/1×7/44

=> r = 847/44

=> r = 19.25cm

VERIFICATION:-

circumference of circle = 2πr

= 2×22/7×19.25

= 847/7

= 121cm

hence verified

thus the radius of the circle is 19.25cm.

now,

area of the circle = πr²

= 22/7×19.25×19.25

= 8152.375/7

= 1164.625m²

hope this helps..!
