the diameter of a circular table top si 80cm. If you put a cloth on top of it how much cloth do you need

Sagot :

In this case, we are finding the area of a a circular table top using its diameter.

The formula is:
A= (π/4) x D²

A= (3.14/4) x 80²
A= (3.14/4) x 6400
A= (0.785)(6400)
A= 5024

So the area is 5024cm²

We will need a circular cloth with 5024cm² to cover the whole table.
