Question

find the radius and diameter of the given following measurements. a) area 1)616sqm​

Answer 1

area=π$r^2$

$616 = \frac{22}{7} × r^2$

$\frac{616×7}{22} = r^2$

$\frac{56×7}{2} = r^2$

$196 = r^2$

square root both side

$\sqrt{196} = \sqrt{r^2}$

$14 = r$

hence radius is 14m

so the diameter would be

14×2 = 28m

Answer 2

We know that, area of Circle = 616m^2

Area = Πr^2

So, Πr^2 = 616m^2

r^2 = 196

r = √196

r= 14m

diameter = 2 × ( radius)

diameter = 28m

So, Radius of the circle is 14m and Diameter of circle is 28m.
