There can be no conversion.A linear foot (or just plain foot) is a measure of length in 1-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.
16.25 cm will be the radius of the circle (32.5 divided by 2) Area of a circle = pi*radius2 = pi*16.252 = 51.05088062 square centimetres So the answer is 51 square metres correct to two significant figures.
It is the equivelent to 51 and 9/32 of an inch or roughly 51 and 1/4
General equation of a circle: x^2 +2gx +y^2 +2fy +c = 0 Points: (6, 3) (-5, 2) (7, 2) Substitute the points into the general equation to form simultaneous equations:- !2g+6f+c = -45 -10g+4f+c = -29 14g+4f+c = -53 Solving the above simultaneous equations: g = -1, f = 3 and c = -51 Therefore: x^2 -2x +y^2 +6y -51 = 0 Completing the squares of x and y: (x-1)^2 + (y+3)^2 -1-9-51 = 0 So it follows: (x-1)^2 + (y+3)^2 = 61 Centre of the circle is at (1, -3) and its radius is the square root of 61
4 foot 3 inches in inches is 51 inches 51 times 3.21 cm per inch = 163.21divide that by 100 = 1.6321 meters
