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

How many square feet are in 1 yard of concrete?
A yard of concrete is a measure of volume. A square foot is a measure of area. A cubic yard is 27 cubic feet of stuff. (3x3x3)To relate volume to area you must extend the area over a third dimension. One square foot that is one foot deep will equal one cubic foot. (1x1x1)So, a yard of concrete is 27 cubic feet or 3 feet tall 3 feet wide 3 feet deep. concrete wieghs 150lbs per cubic foot 27cubic feet times 150 pounds is 4050 pounds. This is 1 cubic yard of concrete.
How many yards of concrete in a 10 ft by 26 ft area?
None. Because 'yars' is a linear measure. You need a 'Cubic' measure. You gave two dimensions a length and a width. However, you also need to know the depth, in order to give you the volume of concrete needed in 'cubic feet'. To convert 'cubic feet' to 'cubic yards' divde cubic feet by '27'.
How are cubic inches and inches different?
Cubic inches are a measure of volume, square inches a measure of area and inches a measure of length.
How much concrete is needed for an area 8' x 4' and 3 deep?
96 cubic feet of concrete
How are the circumference and area the same and difference?
They are not the same except that they relate to plane shapes. The circumference is a one-dimensional measure of the boundary of a shape while the area is the two-dimensional measure of its coverage.
