The radius of a circle is 2 inches. What is the circle's area?

Step-by-step explanation:

The area of a circle can be found using the following formula.

The radius of the circle is 2 inches.

Substitute the value into the formula.

Evaluate the exponent.

Multiply.

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 6 to a 7.

The area of the circle is about 12.57 square inches.

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.
