Question

Find the circumference of a circle that has a diameter of 5. Use 22/7 for pi

Answer 1

The circumference of a circle is $2 \pi r$ since the radius is half of the diameter we can substitute the diameter instead of using 2r. So we get $\pi d$ The we can substitute the given diameter, which is 5 and multiply it by $\frac{22}{7}$ and get $\frac{110}{7}$.
