How much fencing is required to enclose a circular garden whose diameter is 84m?

how much fencing is required to enclose a circular garden whose diameter is 84m?|||You need the circumference of the circle, which is 84*Pi or 263.8m|||The amount of fencing will be the length of the circumference of the circle.


Where C is the circumference and d is the diameter:


C = 蟺d


Plug in d = 84 m:


C = 84蟺 m 鈮?263.89378 m|||To find the circumference of a circle, use the formula C = 2(pi)r


The radius is 84/2 m = 42m


2pi(42)


84pi m= Circumference = Fencing needed.|||the formula is pi x d,do your own homework and learn
