What is the approximate length of the minor arc XY?
A. 28.3 cm
B. 25.7 cm
C. 14.1 cm
D. 56.5 cm

The central angle in radians is (60 / 57.29578)

equals 1.0471975512  radians

arc length = radius * central angle (radians)

arc length = 27 cm * 1.0471975512

arc length = 28.2743338823  =

28.3 cm (rounded)

Answer is A

Step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
