The circumference of a circle with a radius of 2.5 feet can be calculated using the formula:
C = 2πr
where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius.
Substituting the given values:
C = 2 * 3.14 * 2.5 = 15.7 feet
So the estimated circumference to the tenths place using 3.14 for π is 15.7 feet.
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle. In this case, the radius is given as 2.5 feet.
First, substitute the value of radius into the formula:
C = 2 * 3.14 * 2.5
Next, perform the multiplication:
C = 6.28 * 2.5
C = 15.7
Therefore, the circumference of a circle with a radius of 2.5 feet is approximately 15.7 feet when estimated to the tenths place using 3.14 for π.
