if you have a 18 foot diameter circular above dround pool that is $48.43 what is the cost per square foot of this cover?
How many "square feet" are in the pool cover?
area = π * radius2
radius = diameter / 2
radius = 18 feet / 2
radius = 9 feet
area = π * (9 feet)2
area = 81π square feet
So there are 81π square feet in the pool cover.
Now let me ask this...
If there are 2 apples in a basket,
and the total cost of the basket is $6,
how much does each apple cost individually?
$6 / 2 apples = $3 per apple
If there are 81π square feet in the pool cover,
and the total cost of the pool cover is $48.43,
how much does each square foot cost?
$48.43 / (81π) square feet ≈ $0.19 per square foot *thx EP
