Sagot :

Answer:

D. 8pi yd^2

Explanation:

Area of a sector is expressed as;

[tex]A\text{ = }\frac{\theta}{360}\times\pi r^2[/tex]

r is the radius of the circle

theta is the angle substended at the centre

Given the following

r = 9yd

theta = 360-200

theta = 160degrees

Substitute

A = 160/360 * pi(9)^2

A = 4/9*18pi

A = 72pi/9

A = 8pi yd2

Hence the area of the shaded sector is 8pi yd2
