Answer:

5.64 cm

Step-by-step explanation:

1 decimeter = 10 centimeters

1 dm^2 =  10^2 cm^2 = 100 cm^2

Area of circle = 3.14*r^2 = 100

r2= 100/3.14*r^2 = 31.85

r = (31.85)^1/2 = 5.64 cm

Answer:

The radius of circle is 0.17 meters

Step-by-step explanation:

Since Area of circle is given as

Area of circle = pi * r²

So putting the values

0.1 m² = 3.14 *  r²

0.1 / 3.14 =  r²

0.031 =   r²

Taking square root on both sides

r = 0.17 metres
