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 t
he nearest tenth. a 251.2m b 502.4m c 12,352m d 20,096m
2 answers:
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
I believe it’s A but not quite sure

Answer:
315 divide by 7 nevermind
Step-by-step explanation:
The circumference = 2×pi×radius
the small = 2×3.14×4 = 25.12 inches
the medium = 2×3.14×5 = 31.4 inches
the large = 2×3.14×6 = 37.68 inches
