Answer:

2.09 sq. units

Step-by-step explanation:

We can simply use the formula for area of a sector of a circle.

Area of sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]

Where  [tex]\theta[/tex] is the angle and r is the radius.

It is given that the angle is 15 and radius is 4. We plug them in and find the area:

[tex]\frac{\theta}{360}*\pi r^2\\=\frac{15}{360}*\pi (4)^2\\=\frac{1}{24}*16\pi\\=2.09[/tex]

Thus area of sector is 2.09  sq. units.

Answer:

2pi/6

Step-by-step explanation:

If you convert the degrees to radians (15 degrees theta) you get:

15/1 * pi/180 --> =15pi/180 then you multiply by the radius --> 15pi/180 *4/1

this gives you 60pi/180 (don't forget to reduce) =2pi/6

(Sorry this is so confusingly written out. I wish I could have just shown you on paper but just remember that all of the "/" mean a fraction! :) )
