4 and a quarter inches.

Approx 246576 cubic inches.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*4 ~= 125.7 square inches / 144 square inches/square foot = 0.8727 square feet We have 30 such holes so total volume = 30*0.8727 = 26.18 square feet.
V = volume of a cylinder = Pi*Diameter*depth 144 square inches = 1 square foot volume of each hole: Pi*10*5 ~= 157.1 square inches / 144 square inches/square foot = 1.091 square feet We have 30 such holes so total volume = 30*1.091 = 32.73 square feet.
Trypophobia is the fear of holes or objects with holes.

The relevant magnitude is mainly the black holes' mass. Since black holes are the result of collapsing stars, yes, there are black holes with the mass of a star.The diameter is usually taken as the diameter of the event horizon. This diameter is directly proportional to the mass; a supermassive black hole such as Sag A* has a diameter comparable to that of a large star.
Four and a quarter inches. This size was decided on as the first hole cutter that was invented cut holes with a diameter of 4.25 inches. Then when they decided on the standardized rules for golf at st Andrews in 1891, they went with this size.
By the diameter of their event horizon.
The F holes in a cello are called... <drum roll!> F-holes! They are also called 'sound holes', and acousticians might refer to them as 'ports'.
The Minoan Civilization helped in the development oval-shaped holes in their tools to fit oval-shaped handles. Therefore, this stopped the spinning.
