Mrs.penn has a circular tablecloth with a circumference of 29 feet. Which expression could be used ro find the radius of the tablecloth?

f. 29 - 2 pie
g. 29/2 pie
h. 29/pie
j 29 + 2pie

The formula for the circumference of a circle is C=2(pi)r. If we divide both sides by 2(pi) we have:

C/2(pi)=r

Substituting 29 for C we have:

29/2(pi)=r

and therefore the correct answer would be "g."

To find the radius of a circle given its circumference, you can use the formula:

Circumference = 2 * π * radius

In this case, the given circumference is 29 feet. So, we can rearrange the formula to solve for the radius:

radius = Circumference / (2 * π)

Now let's evaluate each expression using this formula:

f. 29 - 2π:
This expression does not follow the correct formula for finding the radius.

g. 29/2π:
This expression represents the incorrect calculation for finding the radius.

h. 29/π:
This expression accurately represents the formula for finding the radius. Dividing the given circumference of 29 feet by 2π will give you the radius of the circular tablecloth.

j. 29 + 2π:
This expression does not follow the correct formula for finding the radius.

Therefore, the correct expression to find the radius of the tablecloth is h. 29/π.
