What shape has both flat and curved surfaces?
cylinder
How is a sphere like a cylinder?
Both are 3-dimensional figures wiith a curved surface.
Is an arrowhead a concave shape?
An arrow can have both concave and convex surfaces, depending in its design.
What time is it when the hour hand and the minute hand are both pointing to the same number?
12:00! It depends what number they are both pointing to.
What is difference between a polygon and plane figure?
A polygon is a plane figure with 3 or more straight sides and angles. A plane figure is a flat enclosed figure made of straight lines, curved lines, or both.
What solids have both flat and curved surfaces?
2
What shape has both flat and curved surfaces?
cylinder
Similarity between convex and concave?
both involve curved surfaces
What is trough cross bedding?
Where only one of both bounding surfaces are curved.
Are the laws of reflection applicable to plane surfaces also valid for curved surfaces?
Yes, the laws of reflection are applicable to curved surfaces as well. The angle of incidence is still equal to the angle of reflection, but both angles are measured with respect to the normal at the point of incidence on the curved surface.
Does a cylinder have a curved and flat surface?
Yes, a cylinder has both curved and flat surface. Considering a solid cylinder standing on its end, the circular base and the circular top are flat surfaces. The surface connecting the top and bottom is curved.
Does the law of reflection apply to curved and flat mirrors?
The law of reflection is valid for any ray of light. So it is also valid for curved and flat surfaces. For curved surfaces, the normal is taken as the normal to the tangent of the point where the light ray hits the surface.
What is the meaning of lens?
A piece of glass, or other transparent substance, ground with two opposite regular surfaces, either both curved, or one curved and the other plane, and commonly used, either singly or combined, in optical instruments, for changing the direction of rays of light, and thus magnifying objects, or otherwise modifying vision. In practice, the curved surfaces are usually spherical, though rarely cylindrical, or of some other figure.

What is a shape with a curved face?
A cylinder has two faces that are both curved.
What is a flat file in metal workshop?
A hand file where both surfaces are flat. Used to file down metal where the surface requires a flat finish. Other files in the work shop are curved concave, curved convex ,triangular and square. Each used to specific shape filing.
Why is the letter A like a flower?
Both the flower and the letter a are curved because the a has a curve and the flower has pedals that are curved.
