Mr. Casa wants to put a fence around a circular space in his back yard for his children to play in. If the space has a diameter of 35 feet, how many feet of fencing does he need?
[tex]C=2 \pi r[/tex] is how you find circumference. If all you have is the diameter then divide it by 2 and plug it into the r spot of the equation and when you do that you get C≈109.96
