how do i estimate # of concrete blocks for a circle 34 feet inside diameter x 10 feet in height with ?

Question

building a circular structure with 8x8x16 concrete blocks using a 34 ft inside diameter x 10 feet in height. how many blocks would i need? consider this a structure with out doors or window openings.

Answer 1

34ft x pi = 106.81ft ID, which is 1282 inches. Divided by 16 is 80.11 blocks. 10ft = 120 inches, divided by 8 inches is 15 blocks high, times 80 = 1200 blocks total.

But allowing for mortar gap of slightly more than 1/2 inch between levels, you'd only need 14 blocks to reach a 10-ft height, so total would be 14 x 80 = 1120 blocks total. And going around with about the same mortar gap would be 78 instead of 80 blocks, so 78 x 14 = 1092 blocks, assuming approximately 1/2" mortar gaps horizontally and vertically.

Answer 2

approx. 510 they come 90 to a cube. id order a few extra...ooops i was
figuring
wrong...
sorry

Answer 3

Are those metric or standard cement blocks?
