The running tracks of two different playgrounds are shown below. Figure A is a semicircle with a diameter of 100 m. Figure B is composed of two semicircles and a square with sides of 100 m. How much farther would an athlete run if they ran around the track in Figure B vs. the track in Figure A?

10157.08 m

Step-by-step explanation:

Find the area of the square, and get 10000, from multiplying 100 by 100. Then, find the circumference/area of the semi-circle as a whole circle. 314.16m. Divide it by 2 and get 157.08 m. Add everything up and get 10157.08 m. Remember, that we aren't calculating the total of both semi-circles because we subtract Figure A from Figure B.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
