Answer:
Cone
Step-by-step explanation:
Rotation means the circular moment of an object about some axis or center.
In the given figure, the shape is rotated along the dashed line.
The size of the object remains same after rotation.
After rotating about the dashed line, we observe that the object formed is three- dimensional and is in the shape of a cone.
Answer:
≈ 35.1 ft
Step-by-step explanation:
The model is a right triangle with ladder being the hypotenuse and the angle between the ground and the ladder is 70°
Using the cosine ratio, with l being the length of the ladder.
cos70° = =
( multiply both sides by l )
l × cos70° = 12 ( divide both sides by cos70° )
l = ≈ 35.1 ( to the nearest tenth )
The ladder is approx 35.1 ft long
