Wut is da approximate circumference of a circle dat has a radius of 90? Use 3.14 fro x and express ur answer to da tenths place

Answer 1

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

\[ C = 2\pi r \]

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

Given that the radius \(r\) is 90, we can substitute that value into the formula:

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

Calculating this step by step:

1. Calculate \(2 \times 3.14\): \[ 2 \times 3.14 = 6.28 \]

2. Now multiply that by 90: \[ 6.28 \times 90 = 565.2 \]

Therefore, the approximate circumference of the circle is 565.2 (to the tenths place).
