Sheldon cuts a circle with a diameter of 14 centimeters from a square piece of felt 15 inches on each side. in terms of pi, how much felt is left over?
show work

The entire area of the felt is 15 x 15 = 225 square inches
The circle cut from the felt =
circle area = PI * radius^2
circle area = PI * 7^2
circle area = 49 * PI
49 * PI =  153.94
Left over felt 225 -153.94 = 71.06

Given that:

The tables values which represents Age and Admission Price is

   Age           Admission Price

under 5                free

  5–17                   $25

18–64                   $40

65 and over          $35

To find:

Domain and range of the function.

Solution:

Domain is the set of input values.

Here, domain is age because age is an independent variable.

Age cannot be negative, so

Therefore, the domain is all number greater than or equal to 0.

Range is the set of input values.

Here, range is Admission Price because Admission Price is a dependent variable.

Admission Prices are free (i.e., 0), $25, $40 and $35. So

Therefore, range is {0,25,35,40}.
