Question

The radius of a circle is 3 miles. what is the circle’s circumference? use 3.14

Answer 1

The formula for the circumference of a circle is:

C = 2πr           [C = circumference     r = radius     π(pi) = 3.14.......]    

You know:

r = 3 miles           and π = 3.14  

So substitute/plug it into the equation

C = 2πr      Plug in 3 into "r" since r = 3, and plug in 3.14 into "π" since π = 3.14

C = 2(3.14)(3)

C = 18.84 miles

Answer 2

We want to find the circumference of a circle given that we know its radius.

The answer is: 18.84 miles.

Let's see how to compute the circumference.

For a circle of radius R, the circumference is given by the formula:

C = 2*pi*R

Where pi = 3.14

Then if the radius of the circle is equal to 3 miles, we can see that the circumference is given by:

C = 2*3.14*(3 miles) = 18.84 miles.

The circumference of the circle is 18.84 miles.
