Find the diameter of a circle with an area of 240.25(3.14) square millimeters

The diameter of a circle with an area of 240.25 square millimeters is approximately:

Step-by-step explanation:

The area of a circle is usually calculated using the formula:

You must remember that the radius is exactly half the radius, so you must clear the radius of the equation and finally multiply it by 2:

Solving for the radius of the formula gives:

When replacing with the provided data, you get:

As you remember, the radius must be multiplied by 2 to obtain the diameter, therefore:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
