Answer:

Radius is 10cm

Step-by-step explanation:

Given that

Area of circle is 314cm sq.

To find radius of circle

Solution

As we know that

area \: of \: circle = \pi \times (radius {)}^{2}

as we know

\pi = 3.14

hence

 {radius}^{2}  =  \frac{314}{3.14}

as there is decimal point in denominator hence

 {radius}^{2}  =  \frac{31400}{314}

by division we get

 {radius}^{2}  = 100cm

as 100 is the square of 10 hence

radius = 10cm

Hence radius of circle is 10cm.
