Question

a pie tin has a circumference of about 25 inches. which is the best approximation for the radius of the tin

Answer 1

Let's model the problem like a circle.

The circumference of a circle is given by:

`C = 2 \pi r`

Where,

r: radius of the circle.

Clearing the radius we have:

`r = (C)/(2\pi )`

Then, replacing values we have:

`r = (25)/(2\pi )`

`r = 3.98 inches`

Answer:

The best approximation for the radius of the tin is:

`r = 3.98 inches`
