Transcript text: Alex has trained his puppy, Popper, to jump through a ring. According to Alex's measurements and calculations, the ring has a diameter of 3.5 feet. What is the ring's circumference (use 3.14 for pi)?
10.99 ft 12.25 ft 11.32 ft 8.75 ft
Solution
Solution Steps
Step 1: Identify the given information
The diameter of the ring is \( 3.5 \) feet, and the value of \( \pi \) to be used is \( 3.14 \).
Step 2: Recall the formula for circumference
The circumference \( C \) of a circle is calculated using the formula:
\[
C = \pi \times d
\]
where \( d \) is the diameter of the circle.
Step 3: Substitute the values into the formula
Substitute \( d = 3.5 \) feet and \( \pi = 3.14 \) into the formula:
\[
C = 3.14 \times 3.5
\]
Step 4: Perform the multiplication
Calculate the product:
\[
C = 10.99 \text{ feet}
\]
