Isaac is also designing a circular serving tray that he plans to engrave around the edge. The serving tray has an area of 3.14 square feet. Using 3.14 for , what is the circumference of the serving tray rounded to the nearest hundredth?

6.28 feet

Step-by-step explanation:

1.) Find the radius.

The area is given, and the formula for area of a circle is A =  Let's substitute.

3.14 =

Divide by pi on both sides

1 =

Find the square root of r

1 = r

The radius is 1.

2.) Find the circumference.

C =

C =

Multiply 2 and 1

C =

C ≈ 6.28

The circumference is approximately 6.28 feet.

the answer is c hope it

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
