Question

What is the circumference of a circle that has a diameter of 1.54 inches?

Answer 1

`c=4.8356` inches

Explanation:

Circumference of a circle is given by
`c=2pir`
where `c` is the circumference, `pi` is a constant number, and `r` is the radius.
Since double of the radius is called diameter. i.e. `d=2r` where `d` is the diameter.
`implies c=pid`
`implies c=3.14*1.54`
`implies c=4.8356` inches
