25 feet is equal to 300 inches. The radius of a hole is half its diameter, which equals 4 inches. The volume of the cylinder is given by the formula v = [Pi]r2h, so the volume of your hole is 3.14 * 16 * 300 = 15080 cubic inches. There are 1728 cubic inches to the cubic foot, so you'll need about 8.75 cubic feet of concrete, which is about a third of a yard. (More exactly, that's a cubic yard, but concrete guys just say "yard.")

Use a masonry drill. If you are drilling a large or deep hole, you can use a hammer drill with a special bit. If the hole is very large, you can rent or hire someone to do concrete sawing.
The recommended depth and size of a concrete footing for a deck post is typically 12 inches in diameter and 36 inches deep. This provides a stable foundation to support the weight of the deck and prevent settling or shifting.
Yes you can.How do i know this?The Model 210B-2 SRA totally pneumatic two-drill system features tri-steering and auto-align features for easy positioning.* 18-in. drill depth with holes from 5/8 to 2 1/2 in. in diameter

For a hole 36" deep X 18" diameter, you would need approx. 1/5 cu. yd. concrete.
To measure the concrete needed for a circular pad:-- Decide how thick (deep) the pad is to be. If it's in inches, divide by 12 for thickness in feet.-- Measure either the circumference or the diameter of the circle, in feet.-- If you measured the circumference, then the cubic yds of concrete needed is(0.00295) x (circumference) x (circumference, again) x (thickness) ... all in feet-- If you measured the diameter, then the cubic yds of concrete needed is(0.0291) x (diameter) x (diameter, again) x (thickness) ... all in feet

None. There is nothing in a hole.
The recommended method for installing a concrete footing for a 6x6 post is to dig a hole that is at least 12 inches in diameter and 24 inches deep. Place a cardboard tube form in the hole and fill it with concrete, making sure it is level. Insert a post anchor into the wet concrete and allow it to cure for at least 24 hours before attaching the post.
