When converting from inches to feet, the measurement in inches, m, of an object varies directly with its measurement in feet, f,
jonny [76]

Step-by-step explanation:

wow, how complicated can one phrase this ...

the point being :

1 ft = 12 in and vice versa (1 in = 1/12 ft)

so, any measurements given in feet but needed in inches need to be multiplied by 12.

and any measurements given in inches but needed in feet need to be divided by 12.

so,

3.5 ft = 3.5×12 = 7/2 × 12 = 7×6 = 42 in

27 in = 27/12 = 9/4 = 2 1/4 or 2.25 ft

{(x - a) }^{2}  + {(y - b) }^{2}  =  {r}^{2}

Where a and b are the x and y values of the centre. So comparing to your equation you can see that a is 2/3 and b is 0
