How many 12 inch blocks to make 4 foot circle?

Answer 1

To determine how many 12-inch blocks are needed to make a 4-foot circle, we first need to convert all measurements to the same unit. Since there are 12 inches in a foot, a 4-foot circle is equivalent to 48 inches in diameter. The circumference of a circle can be calculated using the formula C = πd, where d is the diameter. For a 48-inch diameter circle, the circumference would be 48π inches. To find out how many 12-inch blocks are needed to approximate this circumference, we would divide 48π by 12 to get the number of blocks required.

Answer 2

This is a non-trivial question because the curvature of the circle means that in some cases a whole block is required to cover only a tiny part of the circle.

Covering a circle with a diameter of 4 feet would require 16 blocks measuring 12 inch * 12 inch. This is despite the fact that the total area of the blocks is more than 27% larger than the area of the circle. This was proved by Maurizio Morandi in May 2009.

If the 12 inch blocks are blocks comprising 12 blocks of 1 sq inch each, which can be configured as 2*6 rectangles, or 2+3+3+2+2 shapes, the the problem becomes hugely complex.
