A contractor is tiling the bottom of a round fish pond with 1-inch square tiles that cost $0.12 each. the fishpond has a diameter of 30 inches. how much will he spend on tiles?

about $3.60

Step-by-step explanation:

Because it's a round pond and the tiles are square they might be cut a little but the main point of the question would be the 12 cents PER tile. Per is the one of the words to show multiplication. So you multiply .12 x 30 to get 3.6 and since this is money it would be $3.60

Hope that helps and have a great day!

$84.78

Step-by-step explanation:

If the bottom of the fish pond is round which means it has to be a circle, and to find the space that needs to be covered,you need to find the area of the bottom of the pond.

So it has a diameter of 30  and to find the area you need to find the radius,square it and multiply it by pi.  

The radius will be 15 because the radius is half the diameter.

A= 15^2 * 3.14   we will use 3.14  as an approximation for pi.

A= 225 * 3.14

A= 706.5  

Now after you have find the area multiply it by the amount of money that each tile cost to fin the total amount of money you have to pay.

706.5 * 0.12= 84.78

So approximately you will spend $84.78 on tiles
