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
