Answer:
66π in²
Step-by-step explanation:
Area of one circular base: πr² ⇒ π3² ⇒ 9π
Area of the two circles: 9π + 9π = 18π
We know that the length of the rectangle is 8 in, but we still have to find width. The width of the rectangle is the circumference of either circle:
Width of rectangle: 2πr ⇒ 2π3 ⇒ 6π
Area of rectangle: 6π · 8 = 48π
Total Surface Area: 48π + 18π = 66π in²
Total Surface Area (using the π symbol on a calculator)≈ 207.345 in²
Hopefully this helps!

Answer:
y = 3x + 5
Step-by-step explanation:
add 6x to each side to get:
2y = 6x + 10
finally, divide each side by 2 to get:
y = 3x + 5
Answer:
17.0710678119 and 2.92893218813
Step-by-step explanation:
Theoretically, the wire should come out to be x+y=80,
and the sum of the areas of the squares should be (x/4)^2+(y/4)^2=300.
x/4 and y/4 being the length of one side of the square, we would then square that to find the area. The total wire is all x+y=80. X being one part and Y being the other.
Theoretically, using systems. i found the answers: 68.2842712474619,11.715728752538098
Again, these numbers are very large, and I they actually do both add up to each amount basically perfectly. If your teacher is asking for a rounded answer, that would've been helpful to know. But again, theoretically, those are the answers.
