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 pi.
The formula for the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius.
Given that the radius is 2.5 feet, we can substitute this value into the formula:
C = 2π(2.5)
C = 5π
Now, we can approximate π using the given value of 3.14:
C ≈ 5(3.14)
C ≈ 15.7
So, the estimated circumference of the circle is approximately 15.7 feet.
To find the circumference of a circle, you need to use the formula:
Circumference = 2 * pi * radius
In this case, the given radius is 2.5 feet, and you are asked to estimate the circumference using 3.14 for pi and round to the tenths place.
Step 1: Substitute the values into the formula:
Circumference = 2 * 3.14 * 2.5
Step 2: Perform the multiplication:
Circumference = 6.28 * 2.5
Step 3: Calculate the product:
Circumference = 15.7 ft
Therefore, the circumference of a circle with a radius of 2.5 feet, estimated to the tenths place using 3.14 for pi, is approximately 15.7 feet.
To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius.
In this case, the radius of the circle is given as 2.5 feet. Plugging this value into the formula, we get:
C = 2 * 3.14 * 2.5
C = 15.7 feet
So, the circumference of the circle with a radius of 2.5 feet is approximately 15.7 feet when rounded to the tenths place.
