Question

What si the circumfrence for a circle with a radius of 2.5 feet estimate the circumfrence to the tenths place using 3.14 for pi

Answer 1

you sure?????

Answer 2

To calculate 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 2.5 feet and using \( \pi \approx 3.14\):

\[
C = 2 \times 3.14 \times 2.5
\]

First, calculate \(2 \times 2.5\):

\[
2 \times 2.5 = 5
\]

Now, multiply this by \(3.14\):

\[
C = 5 \times 3.14 = 15.7
\]

So the estimated circumference of the circle is \(15.7\) feet, rounded to the tenths place.

Answer 3

Yes, let's double-check the calculation step by step.

To find the circumference \(C\) using the formula \(C = 2 \pi r\), with \(r = 2.5\) feet and using \(\pi \approx 3.14\):

1. **Calculate \(2 \times 2.5\)**:
\[
2 \times 2.5 = 5
\]

2. **Now multiply by \(3.14\)**:
\[
C = 5 \times 3.14 = 15.7
\]

Thus, the calculated circumference of the circle is indeed \(15.7\) feet.
