Find the circumference of a circle with a radius of 30 feet and DO NOT ROUND YOUR ANSWER!
C = 2πd
Use 3.14 for π

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 30 feet, we can substitute this value into the formula.

Using \( \pi \approx 3.14 \):

1. First, we need to find \( 2\pi r \): \[ C = 2 \times 3.14 \times 30 \]

2. Now calculate \( 2 \times 3.14 \): \[ 2 \times 3.14 = 6.28 \]

3. Next, multiply \( 6.28 \) by \( 30 \): \[ C = 6.28 \times 30 \]

4. Now calculate \( 6.28 \times 30 \): \[ C = 188.4 \]

Thus, the circumference \( C \) of the circle is:

\[ C = 188.4 \text{ ft} \]

Therefore, the answer is:

\[ C = 188.4 \text{ ft} \]
