The circumference of a circle with a radius of 2.5 feet, estimated 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, π represents pi, and r represents the radius.
In this case, the radius is given as 2.5 feet. We can substitute this value into the formula:
C = 2π(2.5)
Using the approximation of π as 3.14, we can calculate the circumference:
C ≈ 2(3.14)(2.5) = 15.7 feet
Therefore, the estimated circumference of the circle with a radius of 2.5 feet is 15.7 feet, rounded to the tenths place.
To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference, π is the mathematical constant pi, and r is the radius of the circle.
In this case, the radius is given as 2.5 feet.
To estimate the circumference to the tenths place using 3.14 for π, we can substitute the values into the formula:
C = 2 * 3.14 * 2.5
C = 15.7 feet
Therefore, the circumference of the circle with a radius of 2.5 feet is estimated to be 15.7 feet to the tenths place.
