The formula for the volume of a rectangular prism is volume = length × width × height. Which of the following is the BEST estimate of the volume of the rectangular prism below?

A. 16 cubic units

B. 54 cubic units

C.90 cubic units

D. 120 cubic units

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
