Geometry help
A small hula-hoop was rolled on the ground. After rolling exactly 6 times, it went 37.7 feet.
What is the Diameter of the hula-hoop?
You got an extra large hula-hoop that has a diameter twice the length of the small hula-hoop.
How far would it go if you got it to roll exactly 8 times?
Be sure to show all your work!!!

A hula-hoop, or circle, has a circumference of pi*diameter. Therefore, when it rolls once it travels pi*diameter distance. So make the equation 37.7 = 6*pi*diameter. Solve for diameter = 2 feet.
At diameter = 4 feet the equation is distance = 8*pi*4 = 100 feet.
