Question

A circle has a circumference of 75.36 yards. what is its diameter? use 3.14 for π and round to the nearest yard.

Answer 1

The circumference of a circle is found by 2πr or dπ. In this case, diameter is asked. So we can use the second formula.

$c = d\pi$
Plug in the values:
$75.36 = d \times 3.14$
Divide both sides by 3.14:
$d = 24$
So, the diameter is 24 yards.
