If the ten books are 28cm thick then the average thickness is 28 (the total thickness) divided by 10 (the number of books).

28cm divided by 10 is 2.8cm.

So the average thickness is 2.8cm!

Average thickness of book = Total thickness/mo. of books
= 28 cm/ 10
= 2.8 cm
Thus, on average, each book has 2.8 cm thickness.

How do I find the radius of a circle
katovenus [111]

Answer:

Step-by-step explanation:

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
