What is the approximate circumference of a circle that has a radius of 90? Use 3.14 for π

Question

and express your answer to the tenths place.(1 point)

Answer 1

To find the circumference \( C \) of a circle, you can use the formula:

\[ C = 2\pi r \]

where \( r \) is the radius. In this case, the radius \( r \) is 90.

Using \( \pi \approx 3.14 \), we can calculate the circumference:

\[ C = 2 \times 3.14 \times 90 \]

Calculating it step by step:

1. Calculate \( 2 \times 3.14 = 6.28 \).
2. Multiply \( 6.28 \times 90 = 565.2 \).

Thus, the approximate circumference of the circle is:

\[ \boxed{565.2} \]
