What is the one shape of cross-section we could create by slicing the cylinder parallel to its base

A circle!

Step-by-step explanation:

Typically, for most 3 dimensional shapes, cutting parallel to the base will result in the shape that the base takes on. Because the base of a cylinder is a circle, the shape of a cross-section parallel to the base of a cylinder would be a circle.

-3.396 = -3.4

-0.708 = -0.7

0.304 = 0.3

0.955 = 1

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.
