Question

Juan and his little brother Miguel ran around a circular track together. Juan ran on the inner track, which has a radius of 30 feet. Miguel ran on the outer track which has a radius of 40 feet. How much farther did Miguel run than Juan?

Answer 1

80pi-60pi

Explanation:

To find how much Juan ran, we must find the circumference.

pi *30*2=60*pi (which is how much Juan ran.)

pi*40*2=80*pi (which is how much Miguel ran)

80pi-60pi would be how much farther Miguel ran than Juan.
