What is the approximate circumference of a circle that has a radius of 90? Use 3.14 for π and express your answer to the tenths place. Thank you

Answer 1

To calculate the circumference of a circle, you can use the formula:

\[ C = 2\pi r \]

where \( C \) is the circumference, \( r \) is the radius, and \( \pi \) is approximately 3.14.

Given that the radius \( r = 90 \):

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

Now, calculating this step by step:

1. First, calculate \( 2 \times 3.14 \): \[ 2 \times 3.14 = 6.28 \]

2. Then, multiply by the radius: \[ 6.28 \times 90 = 565.2 \]

Therefore, the approximate circumference of the circle is 565.2.
