Answer:

47.1 cm

Step-by-step explanation:

The formula for finding circumference is πd. So, plug in the given values and simplify the expression:

d = 15

π = 3.14

15 × 3.14 = 47.1

The circumference of a circle with a diameter of 15 cm and using 3.14 as a substitute for π will be 47.1 cm.

Answer:

[tex]\boxed {\boxed {\sf 47.1 \ cm}}[/tex]

Step-by-step explanation:

The circumference of a circle is the perimeter or the distance around the circle. It is calculated using the following formula:

[tex]c= \pi d[/tex]

The diameter of the circle is 15 centimeters. We are asked to use 3.14 for pi.

  • d= 15 cm
  • π = 3.14

Substitute the values into the formula.

[tex]c= 3.14 * 15 \ cm[/tex]

Multiply.

[tex]c= 47.1 \ cm[/tex]

This number only has numbers in the tenth place, so we don't need to round.

The circumference of the circle is 47.1 centimeters.
