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)
7.85 feet
16 feet
15.6 feet
15.7 feet
The formula to find the circumference of a circle is C = 2πr, where r is the radius.
Using the radius given, which is 2.5 feet, the calculation would be:
C = 2 * 3.14 * 2.5
= 15.7
Therefore, the estimated circumference of the circle to the tenths place using 3.14 for π is 15.7 feet.
To find the circumference of a circle, we can use the formula:
Circumference = 2 * π * radius
Given that the radius of the circle is 2.5 feet and using an approximation of π as 3.14, we can substitute the values into the formula to calculate the circumference.
Circumference = 2 * 3.14 * 2.5
Circumference = 15.7 feet
Therefore, the circumference of the 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 the mathematical constant pi (approximately 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, substituting the given values into the formula, we get:
C = 2 * 3.14 * 2.5
C ≈ 15.7 feet
Therefore, the circumference of the circle with a radius of 2.5 feet is approximately 15.7 feet.
So the correct answer is "15.7 feet."
