Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x
Therefore, the width is 16 cm, the width is 16*3=48 cm
Answer:
It represents a circle of radius 2, centered in the origin of the plane xy and transversal to the z-axis in z=-1.
Step-by-step explanation:
The first thing to notice is that
<u>represents a circle of radius 2</u>, with its center in the origin of a plane xy, of cartesians coordinates.
Starting from here, we have to put the coordinate z, to complete the space R³. <em>Then, the cirlce will "live" into the plane xy, where z=-1</em>.
Finally, we have that this region is a circle of radius 2, centered in the origin of the plane xy, and transversal to z=-1.
