What is the circumference of a circle with a radius of 15 meters? Use 3.14 for pi.
A. 47.1 meters
B. 30 meters
C. 94.2 meters
D. 90 meters
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference, π represents the mathematical constant pi, and r represents the radius.
In this case, the radius is given as 15 meters, and the value of π is given as 3.14.
To calculate the circumference, you can substitute the values into the formula:
C = 2 * 3.14 * 15
C = 6.28 * 15
C = 94.2 meters
Therefore, the circumference of the circle with a radius of 15 meters is 94.2 meters.
The correct answer is option C: 94.2 meters.
The formula to calculate the circumference of a circle is C = 2πr, where C represents the circumference, π represents pi, and r represents the radius.
Given that the radius is 15 meters, we can substitute the values into the formula to find the circumference:
C = 2 * 3.14 * 15
Calculating this expression, we get:
C = 94.2 meters
Therefore, the correct answer is C. 94.2 meters.
