Answer: 100
Step-by-step explanation: 100 divided by 27= 0.27, 23.49x0.27= 6.34.
Three hundred and ten million, seven hundred and sixty three thousand, one hundred and thirty six.
Use elimination
-x - y = -9
x - y = 3
Add both equations
-2y = -6, y = 3
-x -(3) = -9
-x = -6, x = 6
Final answer: x = 6, y = 3
Answer:
Note: The expression "h =300- pi r /pi r" would equate to 299, as written. I find h = (300 - π )/πr to be the equation for height.
Step-by-step explanation:
The total surface area of a sylinder is 2πr(h+r) where h is the height and r is the radius. That consists of top and bottom disks, each with an area of π, for a total of 2π. The side is a continous sheet that has an area of 2πrh, where h is the height. 2πr is the circumference of the can, so the surface area of the side is 2πrh.
The total surace area of a closed cylinder is therefore 2π + 2πrh.
2π + 2πrh = 600
π + πrh = 300
πrh = 300 - π
h = (300 - π )/πr
