The radius of a circular rug is 5 feet. How much ribbing will you need to buy to go around the
rug? Use 3.14 for pi

The length around the rug is the circumference.

The formula is C = 2 x PI x r

C = 2 x 3.14 x 5 = 31.4 feet

For this case we must find the perimeter of the circular carpet.

By definition, the perimeter of a circle is given by:

Where:

r: It is the radius of the circle

According to the statement we have:

Substituting:

So, you need

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

168

step-by-step explanation:

i am pretty sure that the answer is 168
