Answer:

9 pi yards squared

Step-by-step explanation:

By definition, the circumference of a circle is equal to 2pi(radius) or pi(diameter).

Since the circumference is 6 pi yards, we can work backwards to find the area.

Set the equation of the circumference of a circle and the circumference given to you equal to each other in order to find your radius. With the radius we can calculate your area.

2pi(radius)=6 pi yards

Divide both sides by 2

pi(radius)=3 pi yards

Divide both sides by pi

radius=3 yards

Now that we know the radius we can find the area.

By definition, the area of a circle is pi(radius)^2 (This reads as pi times the radius squared)

Squaring the radius is just multiplying it by itself. In this case you would multiply 3 by 3 to get 9.

pi(9 yards squared)=Area

Area=9 pi yards squared

Which function is increasing at the highest rate? A. B. A linear function on a coordinate plane passes through (minus 1, 3), and
xenn [34]

The highest rate on increasing is of 12x -6y = -24; Option B is the correct answer.

The options are given in the image attached with the answer

<h3>What is a Function ?</h3>

A function is a law that relates a dependent variable and an independent variable.

It is asked among the options given , which is increasing at the highest rate.

To increase at a rate , the value of the slope , m should be > 0

For the Option 1

for a straight line function , the slope is given by

m = ( y₂ -y₁)/(x₂-x₁)

m = ( -3 -3)/(2- (-1)) = -6 /3 = -2

Therefore the function is decreasing

For Option 2

12x - 6y = -24

-6y = -12x -24

y = 2x +4

m = 2 (increasing)

For option 3

m = (-4 + 5)/(2-1) = 1

For Option 4

(8,0) (0,-4)

m = (-4 -0) /(0-8) = 4/8 = 1/2

The highest rate on increasing is of 12x -6y = -24

Therefore Option B is the correct answer.
