Answer:
1.29(30) +2
Step-by-step explanation:
First you do 1.29 times 30 that equals 38.7. Then you do 38.7 + 2 and you get 40.7. This means that the total cost is $40.70.
So basically you just need to do the Pythagorean theorem to find the sides of the shaded rectangle, with c being the length of the side.
Small side:
2^2 + 6^2 = c^2
4 + 36 = c^2
40 = c^2
C is similar to 6.32456
Long side:
12^2 + 4^2 = c^2
144 + 16 = c^2
160=c^2
C is similar to 12.64911
And then you just multiply!

Step-by-step explanation:
I'm not sure this is the right answer, because i thought that the air and the metal would be in equilibrium.
So sorry if this is wrong, chemistry isn't my strongest subject.
Answer:
A = 3.9 in²
Step-by-step explanation:
To find the area of the shaded region, you need to find the (1) area of the entire square, then (2) find the area of the 1/2 circles, then (3) subtract them and divide by 2. Because the 1/2 circles are identical, you can combine them and just use the circle area equation.
Area of the Square:
A = l x w
A = 6 in x 6 in
A = 36 in²
Area of Combined 1/2 Circles:
A = πr²
r = 6 in / 2
r = 3 in
A = π(3)²
A = 9π -----> 28.3 in²
Area of Shaded Region:
A = (Area Square - Area Circle) / 2
A = (36 in² - 28.3 in²) / 2
A = 7.7 in² / 2
A = 3.9 in²
