So, for the area of a circle, there should be a line in the middle. Correct?
Well, that line is the diameter. Then cut that in half, so if the diameter is 6, the radius is 3.
Then multiply the the radius by the radius, so 3x3 once you get that, multiply the answer by pi. Pi= 3.14, so if you do 3x3x3.14 you should get 28.26. Hope this helps.
Answer:
0.8
Step-by-step explanation:
9(0.5y+0.4)=590.1y+1.3)+0.3
4.5y+3.6=0.5y+6.5+0.3
4.5y+3.6=0.5y+6.8
4.5y-0.5y=6.8-3.6
4y=3.2
y=0.8

Answer: you would divide the total price of $22.20 by the amount of cartons, which is 12, giving you the unit rate of $1.85 per carton. the unit rate, $1.85 multiplied by 7 is $12.95, so it would cost $12.95 for 7 cartons of eggs
Step-by-step explanation:
Let the number be x
(9+2x)×2= (-3x)+4
18+4x=-3x+4
4x+3x=4-18
7x=-14
x=-2
