Adinner plate fits tightly into a box whose square base has a perimeter of 28 inches.what is the circumference of the plate?

The diameter of the plate would be equal to the length of a side of the box.

Find the length of the box by dividing the perimeter by 4:

28 / 4 = 7 inches.

The diameter is 7 inches.

Circumference is found by multiplying the diameter by pi:

The exact circumference is 7PI

Using 3.14 for pi, the decimal answer is:

3.14 x 7 = 21.98 inches ( round answer as needed.)

Step-by-step explanation:

The formula for the area of a circle is , r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however is the exact answer.
