Is an oval a graph of a function?
No, the graph of an oval/ellipse is not a function because it does not pass the vertical line test.
Order of rotational symmetry on an oval?
An oval typically has two lines of symmetry, which means it has an order of rotational symmetry of two. This means that the oval looks the same after a 180-degree rotation. The center of rotation would be the point where the two axes of symmetry intersect. The oval does not have any other rotational symmetries due to its asymmetrical shape.
How many angles does an oval have?
Oh, dude, an oval has an infinite number of angles if you really think about it. But if you want to get technical, an oval technically has zero angles because it's a curved shape, not a polygon with straight sides. So, like, it's a trick question, man.
What is the circumference of a 15x30 ft oval?
Oval = 2 semicircles connected with two parallel lines which are spaced by the diameter of the semicircle. Circumf. = (Pi x 15) + (2*15) = 15 Pi + 30 = 77.124 (to nearest 3rd decimal). Please note that an oval is not an ellipse.
How do you calculate the shaded area of a half oval?
An oval, or more technically an ellipse, has a long ( major) axis and short (minor axis). If major axis length is a and minor length is b, then area, A is A = pi*a*b /4 where and so the area of half an oval is pi*a*b/8
