John is putting a fence around his garden that is shaped like a half circle and a rectangle. how much fencing will john need? use for .

solution:

john is putting a fence around his garden that is shaped like a half circle and a rectangle.

total fencing that john will require = sum circumference of half circle and perimeter of the rectangle.

suppose the radius of the circle is r , and l and b be the length and breadth of the rectangle.

then the circumferernce of the half circle =

perimeter of the rectangle

total fence=

hence, john will require fencing to fence around his garden

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
