Question

the circumference of a circle is c = πd. what is the approximate circumference of the circle? (use 3.14 for π) 15 ft a 18.1 ft b 23.6 ft c 47.1 ft d 94.2 ft

Explanation:

Step1: Identify the diameter

The diameter \( d \) of the circle is given as 15 ft.

Step2: Use the circumference formula

The formula for the circumference \( C \) of a circle is \( C = \pi d \). We use \( \pi \approx 3.14 \) and \( d = 15 \) ft.
So, \( C = 3.14 \times 15 \)

Step3: Calculate the value

\( 3.14 \times 15 = 47.1 \) ft.

Answer:

C. 47.1 ft
