Answer:
A) 2280 and length is 12mm and width is 190mm
B) 190, 12
Step-by-step explanation:
Area of 1 cylinder: 456
456*5= 2280
38*5=190
diameter:190mm
height:12mm
190*12= 2280
Answer:
0.8
Step-by-step explanation:
-2.8 + 3.6 = 0.8
6 to the fourth power is 1296 because 6x6x6x6 gives you 1296
Answer:
The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.
The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.
2 lengths + 2 Widths = 54. Now, it's just a plug and chug.
2(3 + 3W) + 2W = 54.
6 + 6W + 2W = 54
8W = 48
W=6
L = 3 + 3(6) = 21
To double check: 2(21) + 2(6) = 42 + 12 = 54
The Width is 6 meters, and the Length is 21 meters.
