Find the circumference of a circular field with a diameter of 16 yards.<br> (Let it = 3.14)

Tatiana [17]

Answer:

Hey there!

The circumference of a circle is $\pi(d)$ , where d is the diameter, and $\\\pi$ is a constant roughly equal to 3.14.

The diameter is 16, so plugging this into the equation, we get 3.14(16)=50.24.

The circumference of the circle is 50.24 yards.

Hope this helps :)
