Question

area of circle is 154 cmsq,circumfrrence mn​

Answer 1

$\boxed{area \: of \: circle \: is \: \: \: \: : 154}$

Answer 2

Answer:

Circumference = 44cm

Step-by-step explanation:

Area of a circle is $154cm^2$

If the radius is r cm, then:

π$r^2$ = 154

=> 22$r^2$ = 7x154

∴ $r^2$ $=\frac{7 . 154}{22}$ $= 7^2$

∴ r = 7

∴ Circumference = 2πr = 2 . $\frac{22}{7}$ . 7 cm = 44cm
