Answer 1

Answer: The diameter of circle is 2 yards.

Step-by-step explanation:

We know that , the circumference of a circle = $\pi d$ ... (i), where d= diameter of circle.

Given : Circumference of circle = 6.28 yards

Put this in (i), we get

$6.28=(3.14)d\ \ \ [\text{Use}\pi=3.14]\\\\\Rightarrow\ d=\dfrac{6.28}{3.14}\\\\\Rightarrow\ d=2\text{ yards}$

Hence, the diameter of circle is 2 yards.
