A circular swimming pool has a radius of 20 feet. A fence is going to be built so that there is a 4-foot space around the entire pool. What is the length of the fence? Sunitha solved the problem as shown.

The answer to your question is 150.72 ft

Step-by-step explanation:

Data

radius = 20 ft

fence = 4 ft more

length of the fence = ?

Process

1.- Calculate the new radius

new radius = 20 + 4

                   = 24 ft

2.- Calculate the perimeter

Perimeter = 2πr

π = 3.14

-Substitution

Perimeter = 2(3.14)(24)

-Result

Perimeter = 150.72 ft}

3.- Conclusion

The length of the fence is 150.72 ft

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

a) 32pie square meters
