Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.
X is equal to 22.25 so all you have to do is to fill it in and find the answers
Answer:
34.9
Step-by-step explanation:
Because if you multiply then divide by 2 that will help you alot.
10x2= 20
20x3.14= 62.8
the circumference of the disc is 62.8
<DSR + <SRD + <RDS = 180° (Angle sum property)
2x + x +3x = 180°
6x = 180°
x = 180°/6
x = 30°
So, <SRD = x = 30°
<RDS = 3x = 3(30°) =90°
<DSR = 2x = 2(30°) = 60°
Hope it helps !
