The correct answer is 15.7 feet.
To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference and r is the radius.
Given that the radius is 2.5 feet, the formula becomes C = 2π(2.5)
Using an estimate of 3.14 for π, the calculation becomes C ≈ 2(3.14)(2.5)
Simplifying further, C ≈ 15.7 feet
So, the estimate for the circumference of the circle with a radius of 2.5 feet is 15.7 feet (to the tenths place).
To find the circumference of a circle, you can use the formula: circumference = 2πr, where r is the radius of the circle and π is a mathematical constant approximately equal to 3.14.
In this case, the radius is given as 2.5 feet, and we need to estimate the circumference to the tenths place using 3.14 for π.
To calculate the circumference, you can substitute the values into the formula as follows:
circumference = 2 * 3.14 * 2.5
This simplifies to:
circumference = 6.28 * 2.5
calculating this gives:
circumference = 15.7 feet
Therefore, the estimated circumference of a circle with a radius of 2.5 feet, using 3.14 for π, is approximately 15.7 feet.
