How many pavers needed for a 28 ft diameter pool?

Question

The pavers are 4" X 8" and we want to extend them 32" from the pool. 13.5 feet of the circumference does not need pavers because there is a deck there.

Answer 1

extend 32" = 2ft 8" from a 28' diameter pool makes a bigger circle with 28' + 2 x 2.67' = 33.33' diameter
circumference = pi x diameter = 33.33 pi = 104.72 '

Laying your pavers lengthwise, with the 8" side around the pool will need 104.72 X 12" / 8" ~ 157 pavers

Laying your pavers widthwise, with the 4" side around the pool will need 104.72 x 12" / 4" ~ 314 pavers

Take your pick!

Answer 2

Circumference to pave (adjacent to pool) = 28Pi - 14.5 = ~74'.
Circumference to pave (edge of paved area) = (28+64/12)Pi - 14.5 = ~101'.

I would put the pavers radially from the pool i.e. the longer side perpendicular to the pools edge. Thus you will need 4 pavers from the pool to the edge of the paved area.

Average length to pave is Avg(101 and 74) = 87.5'
Number of pavers needed = 87.5 * 3/ft * 4/radial = 1050

Get 1200 to be sure. Return the balance to Home Depot if any are left over.

Have fun.
