Explanation:


Area=r^2\pi \\Circumference = 2r\pi

The radius is equal to 5 yd. We can use this information to find the are and the circumference. Let's find the area first!


A=(5)^2\pi\\A=25\pi \\A= 78.5

So, the area of the circle is 78.5 yd²

Now, let's find the circumference!


C=2(5)\pi \\C=10\pi \\C= 31.4

So, the circumference of the circle is 31.4 yd
