Question

the area of a circular field is 13.86m². Find the circumference of the field ​

Answer 1

Hi buddy

Here is your answer

Answer 2

we know that

area of circle = πr^2

According to question

πr^2 = 13.86

r^2 = 7*13.86/22

r^2 = 7*0.63

r^2 =4.41

r = sqrt(441/100)

r = 2.1

Now circumfrnce of circle = 2πr

=2*3.14*2.1

= 13.188cm
