Answer 1

Answer: The diameter of circle is 2 yards.

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=(6.28)/(3.14)\\\\\Rightarrow\ d=2\text{ yards}`

Hence, the diameter of circle is 2 yards.
