Respuesta :

The area of the shaded sector is [tex]8\pi[/tex] square units

The area of a sector is calculated using:

[tex]A = \frac{\theta}{2}* r^2[/tex]

So, we have:

[tex]A = \frac{\pi}{2}* 4^2[/tex]

Evaluate the exponent

[tex]A = \frac{\pi}{2}* 16[/tex]

Evaluate the quotient

[tex]A = 8\pi[/tex]

Hence, the area of the shaded sector is [tex]8\pi[/tex] square units
