The function f (x) = cube root of x is an example of a logarithmic function. true fasle

this is a false statement.

the cube root of x also means x raised to the 1/3rd power. in order for it to be a logarithmic function, it needs to grow as a inverse to a power function. since we still have a number raised to a power (albeit a very low power) it is not a logarithmic function.

all logarithmic functions will approach the y axis as they get lower and lower. the cube root of x will actually hit the y-axis at (0, 0)

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
