Henry constructed circle a with a radius of 4 units. he then created a sector as shown in the figure below. which of the following expressions would him find the area of the shaded sector?

option D is the correct answer

Step-by-step explanation:

The shaded portion of the circle is the smaller sector whose radius is the same as the radius of the circle which is given as 4 units. The sector is always bounded by two radii with a common point which is the center of the circle and forming an angle at that point. The given sector forms an angle of 45 degrees.

Area of a sector is expressed as

#/360 × π × r^2 and # is in degrees

Therefore, area of the shaded portion or sector = 45/360 × π × 4^2

= 45/360 × 16π

= 45/360 (16π)

the aswere is the one with all 8's and the second one is with the 10,8 and 6
