Answer:
15092cm^3
Step-by-step explanation:
The total thickness of the strip of metal sheet would be 2*10=20cm
the new radius of the cylinder would be 9/2+20=24.5cm
Volume of a cylinder: ((pi)r^2)h
the height is 8cm
Volume : (22/7)*24.5^2*8
=15092cm^3
First, make sure you convert both equations into standard form. Your two equations would be 2x+2y=38 and -x+y=3. Then multiply the bottom by 2. So your new equations would be 2x+2y=38 and -2x+2y=6. The x would cancel out and you would continue solving for y. y would equal 11 and then you would plug it back into an original equation. When you plug and solve for x, you would get x=8. So your answer would be (8,11)
Answer:
A=115.6
Step-by-step explanation:
Hey There!
So the first step is to find the formula for area of a trapezoid

h = height
b1 = base 1
b2 = base 2
now all we do its plug in the values


Hope this helps!!
Answer:
The answer is 180°
Step-by-step explanation:
Replace the variables in with your angle measurements and add them up. Triangles should end up with a 180° all combined.
