d. 81 pi units2

PLEASE HURRY!! I HAVE LIMITED TIME!! :)

Answer 1

Given:

Given that the radius of the circle is 9 units.

The measure of the angle JHG is 160°

We need to determine the area of the shaded sector of the circle.

Area of the circle:

The area of the circle can be determined using the formula,

`A=((\theta)/(360)) \pi r^2`

where r is the radius

Substituting r = 9 and
`\theta=160`, we get;

`A=((160)/(360)) \pi (9)^2`

Simplifying, we get;

`A=((160)/(360)) \pi (81)`

`A=36 \pi`

Thus, the area of the shaded sector of the circle is 36π units²

Hence, Option a is the correct answer.
