kelso's mom wants to put a floating blanket over the families circular wading pool to keep the heat in and the leaves out the pool has a diameter of 10 feet

A. How many square feet will kelso's mother need?

B. if the pool supply stores charges $0.10 per square foot for the blanket how much will the material for the blanket cost

Area of a circle is A = pi*r^2.  If the pool dia (d) is 10 ft, then the poor rad (r) is 5 ft.  Thus, the area to be covered would be A = pi*(5 ft)^2 = (25 ft^2)*pi.

This material will cost (25 ft^2)*pi*($0.10 / ft^2).

Following are the response to the given points:

It asks us to determine the area of the 10-foot-diameter pool. The formula for the area of a circle:

[tex]\to A= \pi \times r^2 = \pi \times \frac{d^2}{4}\\\\[/tex]

Therefore, the Area (A):

[tex]= \frac{22}{7} \times \frac{10^2}{4} \\\\= \frac{22}{7} \times \frac{100}{4} \\\\=3.14 \times 25 \\\\=78.5 \ feet^2\\\\[/tex]

It will be the blanket's area multiplied by the blanket's cost per square foot. We can express this mathematically as;

[tex]\to 78.5 \times 0.1 = $7.85[/tex]

Therefore, the answer is "78.5 and 7.85".
