What is the circumference of a circle with a radius of 2.5 feet? Estimate the circumference to the tenths place using 3.14 for π .(1 point) Responses 15.7 feet 15.7 feet 16 feet 16 feet 15.6 feet 15.6 feet 7.85 feet 7.85 feet
The circumference of a circle can be found using the formula C=2πr, where C is the circumference and r is the radius.
C = 2π(2.5) (using π = 3.14)
C = 2(3.14)(2.5)
C = 15.7
Therefore, the estimated circumference to the tenths place is 15.7 feet.
To find the circumference of a circle, you can use the formula:
Circumference = 2 * π * radius
Given that the radius is 2.5 feet and using an approximation of 3.14 for π, we can plug in the values and calculate the circumference as follows:
Circumference = 2 * 3.14 * 2.5
Circumference = 15.7 feet
So, the estimated circumference of the circle to the tenths place is 15.7 feet. Therefore, the correct response 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 the mathematical constant pi (approximately equal to 3.14), and r represents the radius of the circle.
In this case, the radius of the circle is given as 2.5 feet. So, you can substitute this value into the formula to calculate the circumference.
C = 2 * 3.14 * 2.5
C = 15.7
Therefore, the circumference of the circle with a radius of 2.5 feet is approximately 15.7 feet.
