To find the circumference of a circle, you can use the formula:
\[ C = 2 \pi r \]
where \( C \) is the circumference and \( r \) is the radius. Given that the radius \( r \) is 90 and using \( \pi \) as 3.14:
\[ C = 2 \times 3.14 \times 90 \]
Calculating this:
\[ C = 6.28 \times 90 \]
\[ C = 565.2 \]
So, the approximate circumference of the circle is **565.2**.
