Question

The circumference of a circle is about 4.6786 yards. The circle's diameter is __ yards. Use 3.14 for π.

Answer 1

`C=\pi d`

is the formula for the circumference of a circle where d is the diameter.

Given,

C = 4.6786

We find d,

`\begin{gathered} C=\pi d \\ 4.6786=3.14* d \\ d=(4.6786)/(3.14) \\ d=1.49 \end{gathered}`

The diameter of the circle is 1.49 yards
