Question

the radius of a circle is 1 mile. what is the diameter?
give the exact answer in simplest form.
miles

Explanation:

Step1: Recall the formula for diameter of a circle

The formula for the diameter \( d \) of a circle in terms of its radius \( r \) is \( d = 2r \).

Step2: Substitute the given radius value

Given that the radius \( r = 1 \) mile. Substituting this value into the formula, we get \( d = 2\times1 \).

Step3: Calculate the diameter

\( 2\times1 = 2 \).

Answer:

2
