Question

the circumferece of a circleis 3.14,find its area​

Answer 1

Answer:

0.85

Step-by-step explanation:

circumference =2*π*r

and area is π*r*r

so now

2*3.14*r=3.14

i.e. r=0.5

so area will be

3.14*0.5*0.5=0.85

Answer 2

Step-by-step explanation:

area = π r ^2

and

circumference of circle is 2π r

sol-

area = c^2/4π= 3.14^2/4π = 0.7846
