Answer:
Total paper required to wrap the gift without any overlaps:
Step-by-step explanation:
Here, we need to find the total paper required without any sides overlapping to wrap the gift.
The gift is of <em>cuboid </em>type.
Given the following:
<em>Length </em>= 15 cm
<em>Width </em>= 30 cm
<em>Height </em>= 20 cm
Please refer to the attached figure.
We can infer that to find the paper required, we actually need to the find the<em> total surface area of the cuboid</em>.
Because the gift wrap will be done <em>on the faces of gift</em> (which is of cuboid shape).
Formula for Surface Area of <em>Cuboid:</em>
Hence, total paper required to wrap the gift without any overlaps:
[wxw+3m=154metresquard ]hence[wxw=154metersduard-3]which is[w=12.42m-3m] the aswer is9.42m
Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:
Where the point (h, k) is the center of the ellipse
In this case we have the equation
Note that its shape matches that of a ellipse with center (9, -2)
Therefore the answer is the obtion C
