Kelso's mom wants to put a floating blanket over their circular wading pool to keep the heat in and the leaves out. The pool has a diameter of $10$ feet.

1. How many square feet of blanket will Kelso's mother need?

   Hint (a):

   She needs enough blanket to cover the area of the wading pool. The area is equal to $πr^{2}$.

2. If the pool supply store charges $$0.10$ per square foot for the blanket, how much will the material for the blanket cost?

   Hint (b):

   Multiply the answer you got in part (a) by $$0.10$ to find the cost of the material for the blanket.

   Answer (b):

   $$7.85$
