The area of a circle is equal to 1 dm². find the radius of the circle.

The radius of circle is 0.17 meters

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

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
