The surface area of a cylinder is the sum of the surface areas of the bases (2 circles) and the side of the cylinder (a rectangle).
The area of the bases is 2 times the area of each base, and each base is a circle,
The area of the side is a rectangle that has as length, the circumference of the base, and as width, the height of the cylinder.
diameter = 2; radius = diameter/2 = 2/2 = 1
height = 16
Answer:
x = 37 y = 12
Step-by-step explanation:
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
x+y = 49
x-y = 25
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
x+y = 49
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
If you divide 156 by 12 it'll give you 13, so there are 13 in each group
Answer:
3.777...
Step-by-step explanation:
You would divide the 2 and once you get the remainder put a decimal after the divisor and keep bringing down 0 until you can divide anymore 3.777...
Answer:
9.0
Step-by-step explanation:
In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long, so
3x-2 = 50/2
3x-2 = 25
3x = 25 + 2
3x = 27
x = 27/3
x = 9
