Which formulas contain a rational number that is not an integer

Formula for the volume of a cone is one.

V = 1/3 π r^2 h.

Step-by-step explanation:

There  some formulas that contain the fractions 1/2 and  1/3.

Area of the sector of a circle = 1/2 r^2 C is one.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
