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)
The formula to find the circumference of a circle is C = 2πr, where C represents the circumference, and r represents the radius.
In this case, the radius is 2.5 feet, so we can substitute that value into the formula:
C = 2π(2.5)
C = 5π
Using the approximation of π as 3.14, we can estimate the circumference to the tenths place:
C ≈ 5(3.14)
C ≈ 15.7 feet
Therefore, the circumference of a circle with a radius of 2.5 feet is approximately 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 the approximation of π as 3.14, we can substitute the values into the formula:
Circumference = 2 * 3.14 * 2.5
Now, let's solve the multiplication first:
Circumference = 2 * 3.14 * 2.5
Circumference = 6.28 * 2.5
Now, let's calculate the multiplication:
Circumference = 15.7
Hence, the circumference of a circle with a radius of 2.5 feet is approximately 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.
In this case, the radius is given as 2.5 feet. So, you can substitute the given values into the formula as follows:
C = 2πr
C ≈ 2 × 3.14 × 2.5
Now, calculate the circumference using the approximation for π:
C ≈ 2 × 3.14 × 2.5
C ≈ 15.7 feet
Therefore, the estimated circumference of the circle with a radius of 2.5 feet is approximately 15.7 feet, rounded to the tenths place.
