Answer :
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.
