The floor plan of a circular pool has an area of 201 square feet. to the nearest whole foot what is the radius of the pool

Step-by-step explanation:

Circle r=c/2pi

Solve for radius

r≈31.99

Circumference  

201

radius of pool comes out to be 8 ft

Step-by-step explanation:

given ,

area of the circular pool = 201 ft².

area of the circular pool = π r².

now,

           π r²  =  201 ft²

             r²  =  63.95

              r   = √63.95

                r   =  7.99      ≅ 8 ft (approximately)

hence,

the radius of required circular   pool comes out to be equal to 8 ft.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
