A circular sector has a central angle of π8 radians and a radius of 4 m. What is the area of the sector?

Use 3.14 for pi. Round your answer to the nearest tenth.
Enter your answer in the box.
Area = __m^2

Step-by-step explanation:

The area of the sector is given by .

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
