Mr. Tomas ereated a 2-foot wide garden path around a circular garden. The radius of the garden is 7 feet. He wants to cover the path in stones. If Mr. Tomas
needs 1 bag of stones for every 6 square feet of path, how many bags of stones
will he need to cover his garden path?

17 bags.

Step-by-step explanation:

We can think of the area of the path, as the difference between the area of a circle with a radius of 9ft (the 7 ft of the circular garden plus the 2ft of the path) and the area of a circle with a radius of 7ft.

Remember that the area of a circle with radius R is:

R = pi*R^2

Where pi = 3.14

Then the area of the path will be:

A = 3.14*(9ft)^2 - 3.14*(7ft)^2 = 100.48 ft^2

Now, we know that Mr. Tomas needs 1 bag of stones for every 6 square feet of path.

Then let's see how many times we have 6ft^2 in the 100.48 ft^2 of the area, this is equal to the quotient between  100.48 ft^2 and 6ft^2

N = (100.48 ft^2)/( 6ft^2) = 16.75

This means that we will need 16.75 bags of stones, but we can not have a 0.75 of a bag, then we should round up our number to 17.

Then Mr. Tomas will need 17 bags of stones to cover his garden path.

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
