Ialso need with this. i'm sorry. i'm just not that good at math.

=38.465 cm^2

Step-by-step explanation:

This is 90 degrees of the 360 in a circle or 1/4 of a circle

The area of a circle is pi r^2

We have 1/4 of the circle, so we have 1/4 of the area

1/4 A = 1/4 pi r^2

        = 1/4 pi (7^2)

      = 1/4 pi *49

      = 1/4 (3.14) *49

    =38.465 cm^2

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. : )
