What is the approximate circumference of a circle that has a radius of 63? Use 3.14 for π

Question

and express your answer to the hundredths 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. Given that the radius \( r \) is 63 and using \( \pi \approx 3.14 \), we can substitute the values into the formula:

\[ C = 2 \times 3.14 \times 63 \]

Now, calculate the multiplication step by step:

1. Calculate \( 2 \times 3.14 \):

\[ 2 \times 3.14 = 6.28 \]

2. Now multiply \( 6.28 \) by \( 63 \):

\[ C = 6.28 \times 63 \]

Calculating that:

\[ 6.28 \times 63 = 395.64 \]

Thus, the approximate circumference of the circle is

\[ \boxed{395.64} \]
