Question

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.

Answer 1

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.
