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 . (1 point)
O 16 feet
O 785 feet
O 156 feet
O 15.7 feel
The circumference of a circle can be found using the formula C = 2πr, where r is the radius of the circle.
In this case, the radius is given as 2.5 feet.
C = 2 * 3.14 * 2.5 = 15.7
Therefore, the circumference of the circle is estimated to be 15.7 feet.
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference, π represents pi (approximately 3.14), and r represents the radius of the circle.
Given that the radius is 2.5 feet, we can substitute this value into the formula: C = 2 * 3.14 * 2.5.
C = 6.28 * 2.5.
C ≈ 15.7 feet.
Therefore, the approximate circumference of the circle with a radius of 2.5 feet is 15.7 feet.
So, the correct answer is "O 15.7 feet".
