Answer:
The area of the circle is 28.26.
Step-by-step explanation:
πr =9.42
Using that, we can find the radius, which will help us find the area of the circle.
9.42/π = 3 (I used 3.14 for π)
The formula for area of a circle is:
πr^2
Plug our values in.
π(3^2)
9π
28.26
The area of the circle is 28.26.
To sum, Min would need to first figure out the radius of the circle, and then use the radius to find the area of the circle. She can figure out the radius by dividing 9.42 by π, and find the area with the formula πr^2.
((-9+14)/2, (-20+12)/2)
(5/2,-8/2)
(5/2,-4)
I'm sorry, I don't know what is being asked.

Answer:
A 500 mg bag of prepackage seeds costing $3.95
Step-by-step explanation:
First, you need to know the amoun of grams in 1/2 kg to find the cost of the sunflower seeds:
1 kg→1000 grams
1/2 kg→ x
x=(1000*(1/2))/1
x= 1000/2
x= 500 grams
Second, you have to find the cost of 500 grams of sunflower seeds:
100 grams → $0.70
500 grams→ x
x=(500 *0.70)/100
x= 3.5
According to this, 1/2 kg of of bulk sunflower seeds cost $3.5 which is cheaper than the 500 mg bag of prepackage seeds that cost $3.95 and this means that the better value is 1/2 kg of bulk sunflower seeds as the amount is also higher as 500 mg is equal to 0.5 grams.
