A circular pool with a diameter of 18 ft will have a uniform
4 ft concrete walkway poured around it. If the concrete cost $4.25 a square
foot, how much will it cost for the concrete?
This can be solve be solving the area of walkway
Area of walkway is equal to = (pi)( 9 ft +4) ^2– (pi)(9ft)^2
= 276.46 sq ft
Cost = 276.46 sq ft * ($4.25 a square foot) = $1174.70
For math- The difference between a value of a variable and another variable which usually ends up to be the variables mean
3/10 * 2/9 = 1/15
There is a 1/15 chance that both of the shirts he grabbed are black....
