Question

The area of a circle is 55.44m find it's radius​

Answer 1

Answer:

given = area of circle 55.45m

area of circle= 55.45

pi r2= 55.45

22/7×r2=55.45

r2= 55.45×7/22

r2= 17.64

r= 4.2m

Answer 2

$\huge\underline\mathbb{Solution}$

We know the formula for the area of circle is πr²

We know the formula for the area of circle is πr²Area of circle = πr²

$55.44 = \frac{22}{7} {r}^{2}$

$55.44 \times \frac{7}{22} = {r}^{2}$

$2.52 \times 7 = {r}^{2}$

$17.64 = {r}^{2}$

$\sqrt{17.64} = r$

$4.2 = r$

$r = 4.2 m$
