Step-by-step explanation:
Ok so what you need to do is first find the area of the circle using π r^2. So π12^2 or π144= 452.389342117 This is the area of the whole circle. To find the area of the sector you have to multiply the total area by 172/360 or 0.47777777777 This will get you 216.141574567 round as necessary but your answer is <span>216.141574567units^2</span>
The answer is 125. Hope it helps you
