Find the area of a circle with a radius of 3 inches. Use 3.14 for pi.

28.26

Step-by-step explanation:

3×3=9

9×3.14=28.26

The answer is 28.26

Step-by-step explanation:

Why? Ok so here it is:

The formula is (pi)(r)squared

In this case, you will replace pi with 3.14 and replace r with 3 because that's the radius.

So it would be (3.14)(3)

You would get 9.42

Now you just need to square it

When squared, you'll get 28.26 inches squared

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.
