Question

dianne runs around a circular track that has a radius of 55 feet. after running three quarters of the distance around the track, how far has she run?

Answer 1

She has run 259.18m

Step-by-step explanation:

Since Dianne is running around the circular track, she is running around the perimeter of the circle.

Now, we know that the perimeter of a circle is given by; P = 2πr

Thus the perimeter of the track = total distance that the man travels = 2 x π x 55 = 345.575 meters

Now, since she has run 3/4 of the distance, thus, she has run;

(3/4) x 345.575 = 259.18m

Answer 2

She has run 259.18m

Explanation:

Since Dianne is running around the circular track, she is running around the perimeter of the circle.

Now, we know that the perimeter of a circle is given by;P = 2πr

Thus the perimeter of the track = total distance that the man travels = 2 x π x 55 = 345.575 meters

Now,since she has run 3/4 of the distance, thus, she has run;

(3/4) x 345.575 = 259.18m
