Michell rollerblades around the circular track. Therefore she travels around the circumference of the circle

circumference is calculated using the perimeter for circles

perimeter for circle is

perimeter = 2πr

where π = 3.14 and r - radius - 80 m

substituting the values in the equation

perimeter = 2 x 3.14 x 80 m = 502.4 m

the circumference of the circel is 502.4 which is the distance she has to skate

answer is b. 502.4 m

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455

Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4

Total number of possible results:

results = 4*455\\results = 1820
