Question

area of a circle is 38.5 sq.m,find its circumference?

Answer 1

Hey dear here is your answer!!!!!

___________________________

We know that the area of circle is - πr²

And we also have been given that area of a circle is 38.5 m².

According to question:-

πr² = 38.5

$\frac{22}{7}$ x r² = $\frac{385}{10}$

Transposing:-

r² = $\frac{2695}{220}$

r² = 12.25

r = √12.25

r = 3.5 m

So, it circumference would be 2πr which is:-

= 2 x $\frac{22}{7}$ x $\frac{35}{10}$

= $\frac{1540}{70}$

= 22m

22m is your answer !
