A round swimming pool has a diameter of 59 ft, you want to paint the bottom of the pool. If each can of paint can cover 300 ft^2. How many cans do you need to buy?

You need to buy about 10 cans of paint.

Step-by-step explanation:

Given : Diameter of round swimming pool = 59 ft

Radius = half of diameter

= ft

Area of circle = , where r= radius

Area of bottom of pool =

Each can of paint cover 300 ft².

So , Number of cans required to cover 1 ft² =

Number of cans required to cover =

Hence, you need to buy about 10 cans of paint.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
