Nataliya [291]

Answer:

The area of the circle is equal to $9\pi$ .

Step-by-step explanation:

Given that,

The area of sector is, $\dfrac{17}{2}\pi$

The central angle is $\dfrac{17}{9}\pi$

We need to find the area of circle.

We know that,

$\text{Area of sector}=\dfrac{\text{central angle}}{2\pi}\times \text{Area of circle}\\\\\text{Area of circle}=\dfrac{2\pi \times \text{Area of sector}}{\text{central angle}}\\\\=\dfrac{2\pi \times \dfrac{17\pi}{2}}{\dfrac{17\pi }{9}}\\\\=9\pi$
