If michelle rollerblades around a circular track with a radius of 80 meters, how far does she skate? use 3.14 for pi. round to the nearest tenth. a 251.2m b 502.4m c 12,352m d 20,096m

I believe it’s A but not quite sure

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
