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>
<em>store y has the better buy.</em>
<em>----</em>
store x -- 3.04 ÷ 3 = $1.01 per bag
store y -- 3.60 ÷ 5 = $0.72 per bag
store z -- $0.78 per bag
store y cost the least so it is the best option.
7. If P = [5,6,7,8). Q = (2,4,6,8) and<br>R=2, 3, 7, 9), then P nQnR=
Setler [38]
Answer:
pnQnR= {}
Step-by-step explanation:
there is no number common in set P, set Q and set R.
So the answer is null
{}
