Acircular swimming pool has a radius of 28 ft. there is a path all around the pool that is 4 ft wide. a fence is going to be built around the outside edge of the pool path.
about how many feet of fencing are needed to go around the pool path? use 3.14

We need approximately 201 ft of fencing

Step-by-step explanation:

We need to find the circumference of the pool plus the fence

C = 2*pi *r  where r is the radius of the pool and the fence

r = 28 +4 = 32

C = 2 * pi * (32)

C = 64 pi

Letting pi =3.14

C = 64*3.14

C =200.96 ft

Rounding to the nearest foot

We need approximately 201 ft of fencing

201 feet

Step-by-step explanation:

Given:

radius=28 ft

path= 4 ft

radius + path= 28+4

                     =32

Circumference of circle= 2πr

c = 2 *π* 32

 = 200.9  

  =201!

201 feet of fencing are needed to go around the pool path!

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.
