4-21. Kelso's mom wants to put a floating blanket over the family's 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 of blanket will Kelso's mother need? b. If the pool supply store charges $0.10 per square foot for the blanket, how much will the material for the blanket cost?

a. 78.6 square feet

b. $7.86

Step-by-step explanation:

a. This simply asks us to calculate the area of the 10 feet diameter pool

Formula for area of circle is ;

pi * r^2 = pi * d^2/4

so Area = 22/7 * 10^2/4 = 78.60 square feet

b. This will be the area of the blanket multiplied by the price per square foot of the blanket

Mathematically, we have that as;

78.60 * 0.1 = $7.86

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
