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

96 cubic feet of concrete

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.

You don't, square feet are a measure of area and cubic feet are a measure of volume.

Impossible!!! Cubic meter is a volume measure and square meter is a measure of area!!!

Square foot is a measure of area. Cubic foot is a measure of volume. They are not equal.

This is not a valid conversion. Cubic units is a measure of volume while square units is a measure of area.

Length x Width x Depth

This is not a correct conversion. Cubic feet is a measure of volume while square feet is a measure of area.

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.

You don't. Square feet is a measure of area but cubic meters is a measure of volume.

Three inches is a measure of distance. It has neither circumference, nor area.

Cubic is a measure of volume and square is a measure of area.

None. A cubic foot is a measure of volume in 3 dimensional space whereas a square foot is a 2-dimensional measure of area. It makes no sense to try to convert from one to the other.

There can be no equivalence. A cubic yard is a measure of volume in 3-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

yes cubic feet are used to find area

Concrete is sold in cubic (volume) measurements not square (area) measurements.

You cannot measure area in cubic meters. The cubic meter is a measurement for volume, so in order to measure something in cubic meters you need three dimensions. An area has two: length and width.
