A circular swimming pool has a radius of 28 ft. There is a path all the way around the pool that is 4 ft wide. A fence is going to be built around the outside edge of the pool path. A circle has a radius of 28 feet. A larger circle goes around the smaller circle that is 4 feet wide. About how many feet of fencing are needed to go around the pool path? Use 3.14 for Pi.

200.96 feet

Step-by-step explanation:

We have a pool with a radius of 28 feet.

They also tell us that there is a path around the pool and its width is 4 feet.

Thus:

The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.

= (28 + 4) feet

= 32 feet

To find the length of the fence, we need to find the circumference of the outside of the pool path. The radius is then equal to 32 feet.

The circumference of the outer edge of the pool path would be equal to the perimeter.

p = 2 * pi * r

replacing

p = 2 * 3.14 * 32

p = 200.96 feet

therefore 200.96 feet are needed

The answer is D, 201

Step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
