1) what is the surface area of a rectangular prism if its height is 6 in and its width 3.5 in and the length is 4 in?
2) what is the surface area of a cube if the length and the width and the height is 9 in?

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.

the answer is y = 11.54

hope this : )
