Acircular marble table top has a diameter of 42 in if the table top cost $280 what is the price per square inch

The price is $0.20 per square inch

Step-by-step explanation:

step 1

Find the area of the circular table top

The area of the circle is equal to

we have

------> the radius is half the diameter

substitute

step 2

Divide the cost by the area to find the price per square inch

therefore

The price is $0.20 per square inch

$0.20

Step-by-step explanation:

We have been given that a circular marble table top has a diameter of 42 in.

First of all, we will find the area of the table top using area of circle formula.

We know that diameter is two times radius, so radius of the table would be:

To find the cost of per square inch, we will divide $280 by area of table as:

Therefore, the cost of per square inch is $0.20.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
